Check your SD card
First up, check your SD card to ensure it’s formatted in the correct file format. While different emulators support different formats, you’re generally safe to go with FAT32 or NFTS. Corrupt SD cards can also trigger this error, so test your SD card with another device after formatting it to ensure everything is in order.
Update Atmosphere and Hekate
Next, make sure that Atmosphere and Hekate are updated with the latest stable builds to ensure they’re compatible with the latest Switch firmware. Make sure you update fusee.bin, and updated configuration files will be required if there’s a change in software versions.
Also, ensure that all required files for the programs to function after the update are on your Switch’s storage drive (or memory card). The update often removes the configuration files required for the emulator to function.

Replace fusee files
In addition to replacing your configuration files, you can also try replacing the currently in use fusee-primary.bin file with fusee.bin and fusee-secondary.bin file with package. This should get the emulator configuration in order and resolve the error.
Disable Auto RCM
Hekate has a feature called auto RCM that automatically boots your console into the default operating system should your modding operating system fail to boot. However, sometimes auto RCM can override the modded OS and go straight to the stock OS. Try disabling auto RCM in Hekate settings to see if that has any effect.

In other terms, Nintendo combines the most delicate features of both systems, allowing users to play home Nintendo games that appear and perform exceptionally on tv while still being portable.
Individuals who seek adaptability in their gaming performance may find its distinctive hybrid style appealing. Nevertheless, the Switch is not without flaws. Because its hybrid architecture isn’t as powerful as, say, a PlayStation or Xbox. Moreover, while Nintendo’s excellent work is to port many 3rd-party games, the Switch can still not play many critical recent titles.

Whenever you are using the Nintendo Switch Console, you might get a message “a fatal error occurred when running fusee,” which means that some software has been hindering the function of the console. The reasons are multiple, but it results in a crash. To learn why “a fatal error occurred when running fusee” occurs? Read the whole section.
Some factors that support this issue “a fatal error occurred when running fusee” are:
1.) SD card error
Whenever SD and MicroSD cards have been installed on various kinds of devices or when they were forcefully removed out of a device while the file was being viewed or transmitted, a corruption error may occasionally be displayed. An incorrect file format might be a problem because each device has a compatibility factor for all hardware and softwares. In this case, if the memory card is not compatible, then the console might face a crash. A corrupt card can also trigger this, but it is easily replaceable.
2.) Outdated Hekate and Platform
An obsolete platform version will affect the functions and hinder the device’s speed. Infuriatingly sluggish hardware is a problem that most gaming areas frequently encounter. In contrast, the majority of gamers believe that using their equipment to the point where it physically stops functioning can help them avoid having to buy new hardware. Sometimes at the storage, insufficient files can trigger problems in the storage drive.
3.) Incorrect Files
The duplicate fusee files could be absent in several files, and it’s feasible. Redundancy, as a result, causes memory waste. Information might not be in a continuous condition due to redundant data. Now due to insufficient data, the structural configuration will not be straight. However, this issue, “a fatal error occurred when running fusee,” is easily solvable.
4.) Problems due to RCM
If your custom operating system fails to boot, Hekate includes a tool called auto RCM that will immediately boot the controller into the standard os. And if RCM fails to do its function or override some settings, it may result in some crash. However, RCM problems are rare in frequency but pretty hectic. Moreover, the solution to this is tedious. Therefore, some efficient solutions for the issue “a fatal error occurred when running fusee.”
These are 4 superb methods by which users can solve “a fatal error occurred when running fusee.”
1.) Verify the memory card
First, ensure the SD card is configured with the appropriate file format. Although various emulators enable various file types, FAT32 or NFTS are typically safe choices. Faulty SD cards can also cause this problem; therefore, after clearing the SD card, ensure everything functions properly by testing it on a different device. Maybe a new memory card will do the work.
2.) Get an Update
Secondly, ensure both have the most recent steady versions installed to check that Environment and Hekate are interoperable with the most recent Switch firmware. Whenever there is a modification in software versions, be sure to update fusee.bin, and new configuration files will be compulsory. Make sure the Switches’ memory disc has all the data necessary for the apps to run just after updates (or memory card). The upgrade frequently deletes the setting files essential for the emulator to work.
3.) Replace Files
One may consider substituting the fusee-primary.bin and fusee-secondary.bin folders with program and fusee.bin in addition to any system settings files. It should correct the problem and put the emulator setup in place. Fixing the problem solves redundancy in the files.
4.) Deactivate RCM
If the custom operating system fails to launch, Hekate includes a tool called auto RCM that will immediately boot the controller into the standard os. However, occasionally auto RCM can bypass the modified OS and go to the familiar OS. Try turning off auto RCM in Hekate’s options to test whether it has any impact. Before doing any of these methods, ensure that the device is connected to high-speed internet.
What do you mean by a fatal error occurred when running fusee failed to identify fs and to open sdmc atmosphere/package3?
Whenever the user gets “failed to identify fs, ” the problem might be with the “fusee-primary.bin file” in addition, a pirated copy of any game could also have a significant impact. In the case of “to open sdmc atmosphere/package3,” the issue arises due to a fake SD card or even if the user fails to install the card properly.
What does a fatal error occur when running fusee failed to mount the sd card and to initialize the sd card 0x00004a18?
The error related to mounting the SD card arises because either the SD card is corrupted or the Sd card reader is faulty. If we talk about the error “to initialize the sd card 0x00004a18,” the reason might be the incompatibility of the SD card with the device and the console. That is SD card installed is not the recommended one.
FAQs on “a fatal error occurred when running fusee”
What are some benefits of the Nintendo Switch Console?
The primary thing a user would notice is the range of configuration the console can provide; moreover, it increases the convenience.
Sometimes issues like “The software was closed because an error occurred” may arise, which means the software has crashed due to corrupted data or lack of updates.
Are gaming switch consoles easily replaceable?
Yes, the consoles are replaceable, but it costs a fortune to buy a new one. It is always recommended that it should be carefully handled.

first boot worked flawless using tegraRcmGui, second time i try to boot i get a black:
a fatal error occurred when running fusée Invalid gpt signature
Already tried formatting sd card and reinstalling everything from scratch but this error keeps coming back.
spend hours online looking for a fix bit can’t find one.
one guy said on another forum:
Are you coming from SXOS?If yes, try this:
- — put your SXOS boot.dat + license in the SD Card root
- — power on, press vol+ button
- — go to option > SX Core/Lite > Clean Up
- — restart, press Vol+
- — Payload > load hekate payload.bin
- — launch AMS emuMMC from there and see if it works
The background here is that SXOS messes with the GPT table which is detected in newer firmwares / AMS, hence preventing a boot. I had this with several other SXOS switches, and cleaning up does the trick.
i can’t find SX Core/Lite > Clean Up , but i do find NAND-> repair GPT.
Tried that but does not fix.
Any suggestions are welcome!

Worked perfectly but i keeped the ExFat.
Yesterday i tried to format my SD card to FAT32.
So i backed up all my folders on my PC, format the Sdcard and back my files on my switch.
And now i have exactly the same error : «a fatal error occurred when running fusée Invalid gpt signature»
I tried to switch back to ExFat and now the error seems happening…
What did you do exactly on SDSetup please ?
I tried the minimal one and seems not to working after booting Hekate.
Did i miss something ?
Thank you in advance.
PS : Ho i forget, i have an EmuMMC which worked well on atmosphere (it was an old EmuMmc converted from SXOS)
PS2 : It reminds me, i had a 29GB partition on my ExFat which wasn’t used before i formated to FAT32, did i make a mess when i formated the whole SD card to FAT32 ?

I have made back ups:
BOOT0 & BOOT1
eMMC RAW GPP
I can boot Hekate but I can’t reach atmosphere. Atmosphere starts booting but something happens and then Nintendo Switch banner appears. The other best attemp I have achieved told me the same message as the OP’s.
I may have messed up with the exFAT and FAT32 formats. My MicroSD card is 200GB, so I get 29 GB on one side and 154GB on the other one. I am pretty lost at the moment. I have decided to erase everything and start all over again another day because I was getting pretty frustrated looking for that mistake I have probably made in one of my steps.
Thanks for any help in advance

After booting up Atmosphere, through Hekate, screen goes black and I receive the fatal error message
How can the issue be reproduced?

Run archive bit fixer in hekate, you have invalid archive bits (probably you use macOS) that are causing atmosphere to be unable to interact with the SD card the way it needs to.
SciresM commented on Mar 23, 2020
If using windows, try deleting atmosphere folder on SD and re-extracting from zip. Your crash report indicates that atmosphere was unable to open the backup path for your PRODINFO — this can only happen when the archive bit is set on the ams folder or a subfolder.

So, a fatal error occurred when running fusee? While dealing with computer projects, you may have faced lags and pauses that create a compulsion to abort the program. As a result, you get redirected to the operating system without completing the running task. Finally, you try to restart the system, but the same error persists, and repetitively the error message gets displayed on the screen.
In technical terms, this is a fatal error we come across when systems crash. As a result, the program gets destroyed.
Rebooting a System
A novice computer user hardly knows how to resolve this issue. The only option they resort to is to reboot the computer. Though reboot seems to be a technical term, it is not so. In a handset, the power button displays a reboot option to restart the system from the beginning. Another option is to abide by system updates. But they offer no permanent solution.
Why Does a Fatal Error Occur in a System?
There is no outright cause to identify the actual reason for a system error. However, software engineers mention some possible reasons for error occurrence.
Firstly, if a user puts in illegal instructions, the system may crash.
Secondly, if users input invalid data or code, the system fails to grasp the command.
Thirdly, in the case of infinity.
Fourthly, if the user abruptly shuts a running program. For example, it can happen during a sudden power cut.
A Fatal Error Occurred When Running Fusee – What is it?
When we think about a real-time platform that functions as a content transformer and manipulator, one of the most popular options is Fusee. It ensures that a digital code can run without any lag in C#.
A fatal error can occur due to signal error, access errors, and extreme memory exhaustion. A deadly mistake leads to program termination. Fatal errors are temporary. However, if they continue to affect system function, it can be due to hardware or software malfunctions.
Virtual Machine Program
A virtual machine program identifies the nature of the error. Then, it locates the error and prepares a crash report.
Easy Method to Fix a Fatal Error in Your System
Error Code
The error code in a device displays relevant information related to a fatal error. As an emergency solution, an error code helps the user understand how to locate and resolve it. The code follows a particular format. For example, it displays two number sets separated by a colon.
Software Update
The primary advice to a user is to update the software. Nowadays, the software version or the apps we install gets updated automatically. You will have to select a preferred time, and the new update will be ready for installation. A manual update option is also available. If the user doesn’t know how to update the software, they can take help from free software updater websites.
Keep the Drivers up to Date
The best way to deal with fatal errors is to update the drivers regularly.
Uninstall Pirated Programs or Software
When we install a new program, we often face difficulty running it. It is because the corrupted files damage the pre-existing files. If such a problem arises, uninstall the app and reboot your system. If the fatal error persists, it is advisable to submit a bug report to the developer.
One thing to remember in this process is to shut down unnecessary background applications. You can zip it temporarily. Running multiple programs at the same time can damage the secured files.
Check Storage in the Device
In a system, excess storage slows down the device. The best way to deal with memory shortage is to free up at least 10 percent of total space. In addition, it enables the device to delete unnecessary cache files.
RAM Memory Test
Users can run a memory test application to check the defects in the RAM.
How to Fix the Fatal Error That Occurred When Running Fusee?
Let us look at some steps that can help us understand how to fix a fatal error.
Step 1
In the first step, check the SD card to check whether it is in the correct format. It is important to note that the form one emulator supports differs from the other. It is advisable to go with NFTS. FAT32 is also an option.
Corrupt SD Card
However, one thing to remember in this process is a corrupt SD card. So, before diving into the first step, check whether your SD card is corrupt. Then, insert the SD card into another device after the formatting is complete to check its status.
Step 2
In the second step, take note of the Atmosphere and Hekate. Update atmosphere and Hekate with the latest version. You can get information relevant to its newer version in its official release version. Check whether they are compatible with the latest firmware.
You must also update Fusee. Another significant aspect in this regard is updating the configuration files. The new configuration will turn compatible with the latest software versions.
Store the vital files required for program processing in the Switch’s storage drive or a safe memory card. This step is necessary because while updating the system. Sometimes a new update discards the stored files.
Step 3
If you want, you can replace the presently in use fusee primary bin file with fusee bin and fusee secondary bin file with package. It may help resolve the error that occurred when running the program.
Step 4
Users unaware of technological knowledge may not know that Hekate has a unique feature of auto boot atmosphere. The unique feature is Auto RCM.
Auto RCM
When the installed operating system fails to function, Auto RCM does its function.
However, Auto RCM can disable the function of the mod operating system. Therefore, experts advise disabling the Auto RCM feature to find whether the fatal error has recurred.
Final Words
Technologies these days are the only resort to dealing with digitalization. However, fatal understanding errors and other issues are problematic for a novice. On the other hand, a tech-savvy individual may have prior knowledge in the software field.
When a fatal error occurs in a system, we tend to shut down the device. But it can cause harm to the device. Following a few steps can prevent a system crash. First, abide by the guidelines to fix the fatal error. If the same issue spring up, try reaching a software developer.
