Rein | Okay, so now when looking through Steam logs, I see lines like those:
Proton: Upgrading prefix from 10.0-200 to GE-Proton10-10 (/home/joe/.local/share/Steam/steamapps/compatdata/0/)
Proton: Prefix has an invalid version?! You may want to back up user files and delete this prefix.
ProtonFixes[41935] WARN: [CONFIG]: Parent directory "/home/joe/.config/protonfixes" does not exist. Abort.
ProtonFixes[41935] WARN: Skipping fix execution. We are probably running an unit test.
I guess protonfixes aren't important in this context, however, I'm a bit curious about the invalid prefix version | 16:26:56 |
