Symptoms

The game hangs and does not launch, an initial configuration dialog appeared on first launch but does not at any point after. No further dialogs appear. Shutting steam will await for Thronebreaker to exit which does so after a few seconds but there is no way to shut the window down through the GUI. The game will remain listed in state Running in the library for periods of >10+ minutes with no further developments.

• Killing any wineserver process causes the dialog box to appear, with the Thonebreaker shield, an error icon and a progress bar which completes.

• Preparing to Launch Thronebreaker: The Witcher Tales appears
• Hanging from this point on

Start with the linked steam-973760.log and the reported system information, then reproduce the hang using Proton 3.7-8 and AppID 973760. Compare the launch sequence with the observed process and journal output; the issue is resolved when the game launches normally and can be closed without killing wineserver.
