Hello I accidentally updated the switch fw to 21.0 so I updated to the latest atmosphere. Some games do boot, like breath of the wild. Some games don't. And it doesn't seem to matter if the game is old or new. Kirby and the forgotten land doesn't work just errors out. Donkey Kong country returns and mario galaxy work. The old mobile port of dragon quest 1 doesn't work. Errors out. Pokemon let's go eevee doesn't work. It errors out when installing. Mario 3d world errors out and crashes the switch what does this sound like
 
 
Have you tried using HATS?

Alternatively, try going into recovery mode. I believe, merely booting into this mode addresses issues, like yours.
Please stop recommending HATS. It ships a bunch of tools that have been modified from the original versions with AI vibe coding. Because he thinks he knows better than everyone else. He's broken these tools and they can actually do physical damage to your console. Like his version of tegraexplorer wipes your battery configuration when you run the reset script. This can cause overcharging on Lites and can cause your battery to catch fire in the worst case scenario. Among other blunders he's done with his pack.

if all else fails, reinstall all the files that won't boot. This is what I resorted to. Also beware of a jksv glitch for deleting save data. make a backup before updating jksv if you use it.

P.S. I should have wrote instructions. It took me a few days to figure out.

I tried everything in this thread, plus I reset the cache in recovery mode. Be careful there (watch youtube if necessary. I updated atmosphere, sig patches, and hekate again. There is also a kernal reset or something in hekate that I used.

Although I use atmosphere and rename to the payload.bin and bypass hekate all together. (I read somewhere this can help with this issue) But that was something I was already doing.

In some sort of all of these steps I got it to a point where when I uninstall the files then re-install they work again.

It was a nightmare. You're not alone.

Best of luck.

P.S. I will forever make a clone of a stable state from this point forward.
