I have the same problem when trying to preview the game in VR mode - completely BLANK project as well as VIRTUAL PRODUCTION TEMPLATE - UE 5.1 Preview 2, Windows 10
What is interesting is that it does not happen when I launch the VR template - the VR template runs OK in VR mode.
Any ideas why that happens?
Below error from console:
