Access violation is triggered when calling Application.Quit() in an OpenXR HoloLens 2 application

Package: OpenXR Plugin


1. What happened
Calling Application.Quit() triggers application shutdown. However, Unity calls back into MicrosoftOpenXRPlugin.dll *after* having downloaded it, thus generating an access violation:

2. How can we reproduce it using the example you attached
Pair a gamepad to the HL, launch the app and press A.
