Hi, i am also having the same issue.
I’m getting the following crash report:
[2023.03.15-22.36.54:900][501]LogWindows: Error: appError called: Assertion failed: ViewIndex != INDEX_NONE [File:D:\build++UE5\Sync\Engine\Plugins\Runtime\OpenXR\Source\OpenXRHMD\Private\OpenXRHMD.cpp] [Line: 3356]
Any help would be much appreciated
