When I use a Controller in 4k, screen goes Green & zooms in

So if I try to run the game in Fullscreen 4k, the second I touch the controller the screen goes Green and Zooms in 2x.

According to other forums, this is caused by the Windows Game Bar, but even if I have this turned off I still get this issue(only in Forza).
Any fixes?
