I am forcing the proton version on launch and I’m not sure what is preventing from this game from launching. When I press play it says “preparing to launch…” for several seconds and then goes away and quits.
Here is the output of steam in the terminal after I try to launch the game
Delete (or rename for backup) the Proton prefix for this game, located at ~/.local/share/Steam/steamapps/compatdata/{APP_ID}/ where {APP_ID} is the Steam application ID, in theory for Among Us it is 945360
Select the Proton 5.0 version in Steam Settings, and do not force another Proton version (official or external like the Eggroll’s builds)
Make sure you have the system and video drivers up to date
Then try to start the game, it will recreate a fresh Proton prefix for the game and according to Proton DB it should work out of the box.
