Symptoms

I've launched HighFleet with default 4.11 Proton. Here is the log file for it.
steam-1434950.log
For a brief moment I saw a black screen, which returned back to my original desktop and then this message appered on screen:

Then I've tried Proton 6.3-5, which hangs with "Preparing to start" Steam window. After killing every process in that hanged group, I tried Proton Experimental. It crashed immediately, without producing any meaningful logs.

Update: Same results after update to the latest versions of everything

Reproduction

Start with the attached steam-1434950.log and the linked system information gist, then reproduce the launch failure using Proton 4.11, 6.3-5, and Experimental as reported. The empty Reproduction section means the launch conditions still need to be documented; done would require identifying a reproducible cause or updating the report with actionable evidence.
