OpenXR extensions not supported by runtime


First of all this is my first post, I hope i’ll provide enough information but it not please tell me.

I’m having a really hard time trying to make a VR Unity Project.
Here’s the set-up :
Windows 11 22H2
Fresh Unity project with Unity 2021.3.22f1 (Build Settings Standalone, Windows 64bits)
OpenXR 1.7.0
MR OpenXR 1.8.0 (added via Mixed Reality Feature Tool)
I’m using the HP Reverb G2 Headset.

I assume I set-up XR Plug-ins correctly according to all the steps I found on official documentation. As a new user I can only put one embedded media, so i’ll decribe:
Checked Initialize XR on Startup, then OpenXR and Windows Mixed Reality feature group. No warning at all.
Added Interaction Profile “HP Reverb G2 Controller Profile”, Checked Windows Mixed Reality (and Hand Tracking, Motion Controller Model and Mixed Reality Features (gray))
In All Features, checked Hand Tracking, Mixed Reality Features (gray) and Motion Controller Model.

Here’s my issue:
Whenever I click play (or try to start the .exe), the app will start as intended, and Main Camera will be tracked by the Reverb G2, but only for a very short time. Within a few seconds, my laptop starts freezing, my cursor position is reset at the center of the screen, then all my screens just black out, before going back to normal. But at this point, there is nothing displaying in the headset and the Main Camera won’t move.

I looked into the EditorLog and that’s what I found (I’m not pasting everything because it’s quite long but I can if you think it is relevant):

And here’s my WMR Runtime

I could not find any help online, when I first set-up VR for Unity 6 weeks ago I had no trouble at all, but now I can’t get it to work, and I don’t know what change exactly (it’s not Unity Version (before updating I tried on 2021.3.18 which was the same back then)), it might be a Windows Update ?
Also I’m still able to run VR on the headset, just not a Unity Project made with current set-up. (I was able to start an old project made with Unity2019)

Any help is very welcome I don’t know what to do.
Thank you!

I don’t really know why, but I updated Windows (to version 2023-04) and set User Experience to optimal quality and suddenly it worked :upside_down_face:

The unsupported extensions seem to be designed for the Hololens, the runtime might be reporting them being unsupported when a different device is used. It should not be an error condition, so it was probably another error that prevented the application from running.
