Steam Deck won't launch

[theboblikejon]

I don't know if this is just a game made beyond the capacity of the Steam Deck. Like a Dragon: Pirates in Hawaii worked fine with no blunders though. So what's the problem? I can get to the start up menu and when I hit "Start Game" it just goes black. I waited 45 minutes for it to start. I am reverifying the files but if this doesn't work I don't know what to do.

It happend to me because of decky framegen. If your using it try unpatching the game, worked for me.

This just happened to me in monster hunter world, and it still wouldn’t launch after unpatching decky framegen, and reinstalling the game twice.

Check your launch options in the steam settings for the game and make sure it’s clean. Uninstalling and reinstalling doesn’t clear that field, so it can be a sneaky culprit.
Mine had some leftover decoy framegen code in there, clearing it allowed me to launch the game.
