I have the problem when I successfully do image tracking on one station in my game then on the next station I wan’t to change the camera direction. But when I set arCameraManager.requestedFacingDirection = CameraFacingDirection.User; Then my app crashes. When there is no successful image tracking then i works fine.

Hello @LeoMH ,

I tested your experience with our BasicImageTracking sample that is available publicly, and I was not able to reproduce your crash using a Samsung Galaxy S21. I wanted to ask you and see you could reproduce this crash in the way that I was testing:

  1. Get the AR Foundation samples (linked to above) to build and run on your Android device using the AR Core as your XR Plugin provider.
  2. Modify the sample to have the ARCameraManager.requestedFacingDirection switch to CameraFacingDirection.User after an image recognized by the sample (for example: Assets/Scenes/ImageTracking/Images/one.png) is tracking in the sample.
  3. See if the app crashes for you.

If you can reproduce this crash successfully, then the next best course of action would be to file this as a bug using the bug reporting facility that is available (as mentioned in the FAQ): Unity QA: Building quality with passion

Mike has it. You might want to attach a debugger to your project to confirm what is causing the crash, as it looks to us like there is some third-party code in your project that is causing this. Unity - Manual: Debug C# code in Unity
