Game's "output_log.txt" from "%APPDATA%\LocalLow\Serious Sim\Radio Commander"

Also tried without DXVK, same result:

Game's "output_log.txt" from "%APPDATA%\LocalLow\Serious Sim\Radio Commander":

output_log.txt

I have also tried to run with PROTON_NO_D3D11 But game exits immediately, I assume there is no earlier direct-x fallback

Symptoms

Application starts with black screen with mouse cursor (which appears to move around the screen fine, for a while) and "jittery" audio playing.

Interaction (clicks and keyboard presses) unresponsive.

Trying to halt the application via the window manager or alt-F4 sometimes freezes Gnome.

Reproduction

Install App.
Try to run

Start by reproducing Radio Commander 871530 with Proton 4.11-7 using the reported launch configuration, then compare steam-871530.log, the DXVK-disabled log, and the game's output_log.txt. Done would mean identifying a confirmed cause and a validated compatibility fix, but the report does not name a source file or failing test.
