Hi there and thank you for the report.
Similar to https://github.com/doitsujin/dxvk/issues/3986#issuecomment-2094847051 this also uses ANGLE d3d11 which requires currently unimplemented DirectComposition support.
Disabling dcomp so it uses a fallback WINEDLLOVERRIDES=dcomp=d or switching to d3d9 --use-angle=d3d9 makes it render.

Compatibility Report
I confirm:
Symptoms
Game launches to a black screen with sound unless you drop down to proton 4.11-13, 5.0-10 and 5.13-6 just crash on launch and 6.3-8 onward launches to a black screen. Checking protondb, the following games from this dev seem to suffer from this.
Qvabllock
Dupio
Gelu
Mumps
Yashik
Illie
I only have the one game to check, but protondb says these all share the same problem and are by the same publisher.
steam-840700.log
Reproduction
Launch the game.
