Having seemingly the same problem of not being able to use VorpX Desktop Viewer. It loads into Windows (showing a black preview thumbnail) and opens inside the headset, but only shows full black on the left eye (though it did show the animated loading icon at some point) and a static frame of what appears to be the cinema environment with a black screen.
Using a Razer Blade 14 with RTX 3070 on Windows 11, no external monitors and using a Quest 2 with Link.
Any idea how this problem can be resolved?
