Symptoms

1. Using Proton 4.11-12, the game works (except for video playback), but under Proton 5.0-1 in stock configuration it fails to launch with Driect3DCreate9::CreateDevice() failed.
   Seeing as PROTON_USE_WINED3D=1 [with 5.0] fixes it, and PROTON_USE_D9VK=1 [with 4.11] shows the same symptoms, I'd say it doesn't like D9VK.
2. In-game videos, e.g. the opening, will be silently skipped out of the box, regardless of Proton version. (Sabbat of the Witch (888790) [same developer & engine] is also affected.) Installing wmp9 enables "low quality" WMV videos.

Start by reproducing the launch failure with Proton 5.0-1 and the reported stock, D9VK, and WineD3D configurations, then inspect the attached steam-1221010 Proton logs. Compare the behavior with Proton 4.11-12 and the reported WMV workaround; done means identifying a confirmed compatibility cause and a reproducible path to launch the game and handle its videos.
