W11 DreamFall TLJ starts to run and then screen goes blank

Hello. New user here. Attempting to run Dreamfall TLJ from Steam. I have a high powered PC running Windows 11. Put it in Windows XP SP2 mode. When I run the program it starts to run the opening sequence and then is removed from the screen. I still have the icon in the icon tray. When I click it, the program tries to run again, but then it is removed from the screen again. And oddly, a copy of the start bar shows up 1/3 the way up the screen.

Anybody had this happen or know how to fix it?
