OpenXR plugin crashes Unity on play with no Oculus connected but OVR service running

[Samuel-Therrien-Beslogic]

To replicate:

1. Configure Unity Project Settings to use OpenXR:

• "[...] > XR Plug-in Management > Initialize XR on Startup": Yes
• "[...] > XR Plug-in Management >Plug-in Providers": OpenXR (Oculus is unchecked and grayed out)
• "[...] > XR Plug-in Management > OpenXR > OpenXR Feature Groups > All Features > OculusXR Feature": Yes

2. Open the Oculus companion app
3. Ensure no VR headset is connected.
4. Press "Play" in Unity (you don't even need a rig in your scene)
5. crash

More information:

Note that this crash does not happen if the OVR service is not running. If OculusXR Feature is off when pressing "play" in Unity, but subsequently turned on afterward through the popup that appears, it won't crash. (but of course will crash if you press "play" again is it is now turned on)
