I didn't have that problem with the beta. I haven't bought the full game yet. In general you should still be able to make Steam use the Windows version instead of the Linux version. This is done by right clicking the game and selecting properties. Under compatiblity there should be an option to force the use of Proton.
have u bought the new game and tried it
For me Steam refuses to run proton and thinks sf6 is a native linux game, did you have that issue as well?
