Symptoms

Able to host and run a game solo with no issue, but if a player attempts to join. The game crashes. Attempting to join another host through any method will also result in a crash.

Reproduction

Either host a game and have a player join the lobby or attempt to connect to another host via the server list, steam game invite, or console command.

Could you please attach the compressed log from PROTON_LOG=+steamclient %command% ? The log may be big but those compress very well.

Nvm the logs, this should hopefully be fixed in the just updated Proton Experimental [bleeding-edge] branch (see https://github.com/ValveSoftware/Proton/wiki/Proton-Versions#proton-bleeding-edge for how to opt into it).

I can confirm bleeding-edge fixes the issue even in The Riftbreaker [coop_beta]. Thank you!

Bleeding edge fixes this issue for me, but seems to cause a regression - game crashes on launch unless I set PROTON_USE_WINED3D as a launch option. It does not require that normally.

Should I open a new issue for that?
