OpenXR Issue

I am currently trying to use OpenXR with VTK instead of OpenVR for VR support and I’ve run into an issue where the OpenXR initialization fails. I have tried to start OpenXR manually via the vtkOpenXRManager class, but this did not change anything. Here are the specific errors I’m encountering:

The following line is also printed repeatedly in the console:
Error [GENERAL | xrPollEvent | OpenXR-Loader] : No active XrInstance handle.

Does anyone have any suggestions on how to resolve this?

Could be the same issue I had with OpenXR SDK version 1.1.36.

As a workaround, for me it works to downgrade to OpenXR SDK version 1.0.34.
