    check registry under 
    HKEY_LOCAL_MACHINE\Software\Khronos\OpenXR\1\ApiLayers\Implicit
    and see if anything there isn’t pointing to ProgramFiles.
    It works!

I found more correct reason!
It's happens when I initialize stereo layer.
In begin play, there's a webview used widget component and stereo layer.
And I guess it's make some problem to rendering pipeline.

    Additional guess.
    Unreal Command Console and SlateUI doesn't show up in VR.
    I Tried changing XR API
    Oculus OVRPlugin + OpenXR Backend -> Epic Native OpenXR with Oculus vendor extensions,
    And it solved problem. but still when I open the stereo layer, It will make crash.

     

    Error: appError called: Assertion failed: ClearValue.ColorBinding == EClearBinding::EColorBound [File:D:\build\++UE5\Sync\Engine\Source\Runtime\Windows\D3D11RHI\Private\D3D11Commands.cpp] [Line: 1069]
    Texture: XRSwapChainAliasedTexture does not have a color bound for fast clears 


    Some guys said It can solve by turn off the motion blur, but it's not helped me.
    Anyone who know this?
