I have the same problem. Trying to solve it I have reinstalled and now in normal OpenBeta all works fine (even with XRNeckSafer), but in the MT version it is upside down and looking to the front of the plane/hangar and not to the menu. It is Like in Diamondviper pictures. I'm going to try with WMR Debug Tool... Any other fix for this problem? Also HP Reverb G2 here and RTX 3090.
Thank you in advance.
