Unity Crash when entering Play Mode - Unity XR VR

2.7k views Asked by At

Unity is crashing when entering the play mode.

  • This does not happen if my Quest 2 is connected to Unity
  • I use the Open / Oculuus XR Plugins
  • I use the Sample Controller example with some custom code
  • Attached to this, you may find the Input

Does any of you have similar issues? How to best debug this error? It could have something to do with finding the device when none is connected, but I could not find anything.

Fabian On BEST ANSWER

I have found a workaround to test in the editor without connecting the glasses. Disable "initialize XR On startup" in the XR Plug-in Management when only testing in the editor.

Martin On

1.Back-up your project. 2. Cut the Library folder and paste it on folders outside your project (desktop/anywhere) 3. Open the project. Unity will resolve the packages and open the project.
