Symptoms

After attaching Proton to the game, the game never launches again and swapping/removing Proton from compatibility layer doesn't help at all.

Reproduction

Set the compatibility tools to any Proton you want, then launch the game and it won't run.
The game is free, so you can even do it yourself. Simply install the game and launch it to see that it works, then add compatibility with Proton and launch it again to see that it no longer works. You can now remove the compatibility with Proton, but the game still won't launch.

Edit: Actually managed to make it work with Proton 6.3.5. I simply swapped it to that one and it worked. Took me literally 1 hour to figure out, but actually someone in the Steam forums helped me to find out Steam uses a default proton to run games. I actually didn't know that.
Edit2: Though, the framerate seems quite poor. Not unplayable, but you can see that it loses frames sometimes. I assume there was an update to Proton yesterday because two days ago (25th June) it worked smoothly.

Start by reviewing the attached steam-1397920.log and the reproduction steps for Mr. Mine (Steam AppID 1397920). Compare launching the game with the reported Proton versions, including Proton 6.3.5, and verify whether the failure and frame loss still occur. Done means the compatibility behavior is reproduced and a specific, current failure is identified.
