Game loads for me but alas no controllers. Make sure you’ve selected all the platforms and profiles you want to support in the OpenXR settings:
- Project Settings > XR Plugin Management (pick platforms and plugin providers), and
- Project Settings > XR Plugin Management > OpenXR (Interaction Profiles section)
I’m on WMR and HP G2, for reference, which has a special plugin you have to install for full support, but I think should get basic support with the Microsoft Motion Controller interaction profile
