When the model target is tracked and I exit play mode in Unity, I receive an exception:
Exception in callback: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> UnityEngine.MissingReferenceException: The object of type 'DefaultTrackableEventHandler' has been destroyed but you are still trying to access it.
I don't have any exception when I run the same scene with an image target. What could be the issue?
I am using:
- Vuforia 7.0.47
- Unity 2017.3.1
