Did some investigation after I sobered up. It looks like the problem is incompatibilities between Steam Beta Client and current protontricks.

Per https://github.com/Matoking/protontricks/issues/304 recent changes to the Steam Beta Client appinfo.vdf, which has changed rather dramatically, cause issues with the way protontricks parses the appinfo.vdf.

Current fix is to downgrade from Steam Beta to the standard Steam client.

Also, its totally fine if you want to re-open this for tracking, I just figure since it's protontricks and not this script at fault it should be closed.
