I'm trying to play Coffee Talk, and after playing smoothly for the first few hours, the game started crashing. When it crashes, the game freezes and doesn't continue in any way. The window stays open unless I force-close it.
I've tried several settings, including using CachyOS Proton version, which didn't work. I tried enabling and disabling UMU, using Proton-GE-latest (v10), and Proton-GE-9.25. I've tried combining these steps in different ways, but nothing worked.
