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.
Update Atmosphere and Hekate
Next, make sure that Atmosphere and Hekate are updated with the latest stable builds. Also, ensure that all required files for the programs to function after the update are on your Switch’s storage drive (or memory card), as the update often tends to remove the configuration files required for the emulator to function.

Replace your configuration files
Since the error indicates a problem with configuration files, try replacing the ones you currently have with the ones you got with your fss0 build to see if that gets things going.
Check the EMUMMC partition
Sometimes, during partition creation, the EMUMMC partition is the only one that remains with data, meaning all other files and folders, including Atmosphere, are deleted. Check your SD card’s root folder and if you only have the bootloader and EMUMMC, try installing Atmosphere again to see if that helps.
Replace fusee files
In addition to replacing your configuration files, you can alsy 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.
