i installed an addon for a game (flight simulator x), but the game crashes when i select it. adding PROTON_LOG=1 to the launch options doesn’t give any useful info, though. i’ve dealt with similar issues before on windows but fixing those issues required me to use the event viewer and i don’t know if wine/proton has a similar program to view the event logs
I think you can set the
WINEDEBUG=+eventlog
environment variable to make Windows Event Log entries appear on stderr (the standard error stream). You can normally see this output if you run Steam from a terminal window. You may be able to redirect it to a file using Steam launch options, but I’ve never tried it.
