Hi. I am trying to get the Godot OpenXR demo application running natively on the Vive Focus 3 but calls to xrEnumerateInstanceExtensionProperties appear to be returning a null xrResult which according to the Khronos documentation should not be possible (xrResultToString(3) (khronos.org)). Is this a known issue? I am running VIVE Focus 3 Software - 5.0.999.558 - July 19, 2022 Thanks
