VR issues

I'm not sure if this is a bug or not.  But I purchased both F! 23, and F! 24 on steam.  Everthing was fine up until about two weeks ago.  Now neither of the games work in VR along with many other VR games.  Steam seems to be giving me the runaround trying to say it is a windows mixed reality problem when I know **bleep** well it isn't because other VR games, but ony a few are stull working in vr.  By the way, ALL of my VR racing sim games are having the same problem.  Is there some commonality with all these sim games?
