I just got a Samsung Odyssey. I meet all the requirements. Got all the updates. Device manager say everything is working properly. The Mixed Reality Portal automatically opens when I plug in the headset. It says I'm good to go. All check marks. I then click the next button. It then starts loading and says "Something went wrong and we couldn't start Windows Mixed Reality". No error message. The audio works and pressing the volume buttons show the volume bar on my desktop. However, if I boot into BIOS the headset works. It'll show my BIOS screen in the headset. When the PC gets to the login screen it shuts off. It also works in safe mode and shows my desktop, but not in VR. The headset also turns on when I use AMD Eyefinity. But only as an extended screen.
