Symptoms

Start the game, first thing that pops up is a launcher to configure settings.
When you hit play in the launcher, the game will try to start but will give an
critical error.
If you try to continue or ignore it, the game still wont start and the window stays inactive.

Reproduction

1. Install game
2. Launch game
3. Configure settings in the launcher.
4. Click on the play button in the launcher.
5. The game will try to start, but will fail with an critical error.

Start with steam-16720.log and the linked system information, then reproduce with Proton Experimental using the listed five steps. Done means the critical error and inactive window are explained and the game launches, but the report names no source file or test to guide a code change.
