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

Also tried without DXVK, same result:

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
