You haven't given us much detail as to what your setup is.

Are you using EmuNAND? With an updated SysNAND and EmuNAND <= 8.1.0, Atmosphere will crash on boot if there's a cartridge in the game slot. This is due to an update to the game slot's firmware.

Either way, I'd just move or rename your atmosphere folder, and then download the latest version of atmosphere from the Github repo:
https://github.com/Atmosphere-NX/Atmosphere/releases/latest

Make sure you also replace fusee-primary.bin on whatever you're using to push the payload. This should get you back up and running, then make sure to install sigpatches if you need them.
