Reproduction

Start the game.

Misc

This game is pretty much an enhanced version of the original game, Fairy Fencer F (347830), which has a separate Proton issue here https://github.com/ValveSoftware/Proton/issues/1852.
An unconfirmed list of the differences can be found on this discussion.

I also have the previous game, but it's too big for me to spend internet bandwidth to also download & install.
If it's merely to provide a Proton log, I thought it would be wiser to make one for this game instead, as it's a better one to play once the issue is solved (I knew it wouldn't work beforehand).

Anyways, I think the issue is related with all the current playback issues (https://github.com/ValveSoftware/Proton/issues/1464). I can find mf.dll and mfplat.dll on my Proton log. I'm guessing the game immediately starts with a cutscene, hence the immediate black screen and crash.

Start with the attached steam-524580.log and reproduce the black screen and crash using Proton 4.2-3. Compare the mf.dll and mfplat.dll entries with the related playback issue #1464, then document a verified cause or compatibility result for this game.
