Proton log, PROTON_LOG=1 %command%

Symptoms

Crashes immediately on startup with the following error in the Unity log:

UnityPlayer.dll called a function with an invalid parameter in module UnityPlayer.dll at 0033:80b77b8e

Removing kernel32.dll changes the traceback, but the game still crashes.

The crash seems to be system config specific, this is not the first Unity game that fails like this but has green reports on ProtonDB.
It looks like it might have something to do with the following quirks of the config:

• two graphic cards/multiple sound devices, issue reproducible on both graphic cards;
• no pulseaudio, only ALSA.

^ That said, I'm not sure how to dig deeper and would appreciate some pointers for figuring out what exactly causes the crash and possibly finding a work around.

Reproduction

Start with the linked Proton log and Unity log for Steam AppID 1274490, then compare the crash under the listed Proton versions and with kernel32.dll removed. Investigate whether the multiple graphics/audio devices or ALSA-only setup consistently affects startup. Done means identifying a reproducible cause or a documented workaround for the UnityPlayer.dll crash.
