Symptoms

After the unity splash green the game is unresponsive and shows it's running at 1 FPS. It appears to be an infinite loop

Reproduction

Just launch the game.

The first scene loads a Mirror networking manager which seems to be the cause of the issue in newer versions of Proton

These are the 7.0 proton logs that doesn't work

Start by launching Witch Slide (Steam AppID 1834530) under Proton 7.0 and compare its behavior and logs with the working Proton 6.3 report. Use the linked logs to investigate the suspected Mirror networking manager issue; done means the game launches past the Unity splash instead of remaining unresponsive at 1 FPS.
