Please describe your issue in as much detail as possible:

Seemingly at random, maybe coinciding with a reboot or update, no steam games using proton work. All games tested were previously known to work using my hardware and packages.
Example log
I've noticed an error that may be of note, no idea if its actually important:
495.234:0020:00d4:err:winediag:nodrv_CreateWindow Application tried to create a window, but no driver could be loaded.
495.234:0020:00d4:err:winediag:nodrv_CreateWindow L"The explorer process failed to start."

Steps tried:

• Reinstalling / updating all graphics drivers / libraries
• Reinstalling steam
• General system update
• Reinstalling games, proton, and steam runtimes

Steps for reproducing this issue:

1. Launch any game using proton
