Since this morning I crash/get kicked on first launch on my steam deck I first thought it might be because it didn't have much power left but I retried a few mins ago with full power and on potato settings that isn't the issue.
So what exactly happens is: I join be there about half a min then my screen freezes in-game (I can still use my home menu and stuff outside of the game) and I'm back at the main menu - only ever happens at first launch after turning my steam deck on (for now at least)
Note: I recently updated my steam deck but yesterday it still worked fine
