It's the video codec, or the playback engine, or whatnot, it was changed with the 64bit version of the game (unfortunately?) and even with ProtonTricks by installing all available codecs, there's no way to make it work.
I'm pretty sure it's related to video codecs or video playback engine because when I compare the logs between the 32 and 64 bit version of the game initialization, they are the same logs but the 64 bit version stops right before the video playback initialization stuff of the 32 bit one.
It would be great to be able to have this, as the 64 bit patch offers much better CPU performance, something crucial for the Steam Deck... (yes some levels drop frames hard due to CPU bound situations).
