Symptoms

The game as if it wanted to run on proton 5.0 on other versions of the proton does not respond.
After turning on the proton 5.0 it shows a black background with no sound in full screen, but after about 5 or 6 seconds everything turns off and the system desktop is shown.

Start with the attached steam-1478650.log and reproduce the launch behavior using Proton 5.0 and the other Proton versions on the listed Manjaro system. Compare the black-screen shutdown across versions; done means identifying a confirmed compatibility cause or documenting a verified fix for the failed launch.
