The problem is identical to the one of the "sister" game "Giana Sisters: Twisted Dreams (223220)"
(https://github.com/ValveSoftware/Proton/issues/1658)
Like described here
the game freezes with a black screen when trying to load the intro wmv
(010c:fixme:wmvcore:WMReader_Open (02160740)->(L"data_common\\BFG Logo 1080p.wmv" 4A256270 00000000))

The game starts fine (showing a black screen instead of the video though) when copying "WMASF.DLL" and
"WMVCORE.DLL" from Microsofts MP10Setup (wmp10 - removed upstream) into the game directory and starting the game exe directly instead of the forced launcher (I use my steamtinkerlaunch for this)

A bit sad that those gems simply don't work just because of some useless 10 seconds intro videos.
As implementing the missing wmp10 functionalilty in wine probably_(?)_ isn't easy (upstream bug: https://bugs.winehq.org/show_bug.cgi?id=38278)
maybe adding a game specific patch (for 246960 and 223220) skipping WMReader_Open would be a valid solution.

Edit:
ffmpeg -ss 00:00:00.00 -to 00:00:00.01 -i BFG\ Logo\ 1080p.wmv -c copy BFG\ Logo\ 1080p_dummy.wmv
generates a very short, compatible dummy intro video (the files need to be renamed of course :))

Start by comparing the WMReader_Open failure and workaround with issue #1658 and Wine bug #38278, then reproduce the intro-video load using Proton 6.3-5. The report identifies BFG Logo 1080p.wmv, WMASF.DLL, WMVCORE.DLL, and the game executable; done means the game starts without freezing while handling the intro video.
