@benis_redux There's a wangblows media software called Microsoft Media Foundation, the middleware ILCA added to unreal engine calls for whenever a cutscenes play. It handles like the h264 audio and video playback.
This program I believe fails to load sometimes when called in WINE.
I had a 🥷 change launcher binary to have this media program loaded more persistently so that it's less likely to not be ready when needed.
That appears to have fixed it. But I'll know when heavens feel tests it. If it works I'll publish the fix on protondb and then get C&D by scamo legal team maybe.
