I can confirm that adding this command to the Steam command line "PROTON_USE_WINED3D=1 %command%" resolved the crash after launcher play.
Set compatibility to experimental.

Game pretty much runs smooth, however, I don't see any of the videos played in the training missions. I hear the audio, but I do not see any video. I will update as I play more. So far seems good. no jitters, stutters or other real "Unable to play" Problems.
Discovered that Alt-Tab out of the Game prevents you from being able to get back in to the same window with out shutting down and restarting.
