Description

Proton versions-all
games-all when using proton

For any game I try and open with Proton, it says playing for a few seconds, then stops. I'm unsure where the issue lies as when reinstalling my OS (linux mint Mate), it works fine for about 2-3 runs before failing to work entirely.
Attached is the log file for FFXIII.
steam-292120.log
I tried looking online for pid 111642 != 111641, skipping destruction (fork without exec?), but all I could find was someone saying it wasn't related to Proton, and only a part of the game.
