This means that the XrInstance handle used in the connect handler is invalid.
The XrInstance that is being used is cached in FHolographicRemotingPlugin::PostGetSystem, which is called when the engine initializes, so it should always be available.

Can you share how you are setting up your project/ actions you take before you get into this state

[duanhong169]

Just created a brand new project, then enable the Microsoft OpenXR plugin, "Enable Remoting For Editor", then click Connecting..., crashed. Now I'm using UE_5.0.3.

Tried to find the reason by check the source code, seems that FHolographicRemotingPlugin::PostGetSystem is never called.

Hi @duanhong169 I have the same problem. Have you solved it?

[duanhong169]

@amao6666 No, I still use the old plugin "WindowsMixedReality"

[HeberRyan]

Same Problem Here. Also Using The brand new default projects with the Microsoft OpenXR plugin, it crashed for both in the source code version and the standard version of UE 5.1.
