I've been gaming on Linux for several months now without much issue, but overnight all games that use proton have stopped launching. I was playing ME3 last night with no issue, went to bed, woke up, and nothing worked.
I am on Fedora 43 using the steam package from the repository (not the flatpak).
Symptoms:
- Every proton game that I've tried is affected
- Games with native linux clients work fine, unless forced to use proton
- Some games will just say "launching" forever, some will say that they're running, but never actually start.
- Downloading an affected game ends with "finishing" forever
- This appears to affect every version of proton
- This happened after attempting to stream to
