I have a WMR Samsung Odyssey headset that has been crashing after the update. I tried the workaround suggested above and turned off my VFR Map and ATC windows which were open when the sim begain, one of which was on a second screen and got the VR to work at least for awhile. As I was flying the pattern the image sometimes paused and restarted, then crashed to the desktop. But at least I got into the sim. I also tried one of the landing flights and that seems to work well with no problems. Before closing the VRF and ATC windowsI it kept starting into VR & then keeps jumping back & forth to the Windows Mixed Reality Portal for about 15 seconds, then crashes FS2020 to the desktop.
