await CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () => OnFaceDetected(false));

System.NullReferenceException: Object reference not set to an instance of an object.

but when I run the app wihtout the assigned access all works fine

This has nothing to do with threads. You tried to acces an empty variable. Debug your code and check which of the objects is null – Panagiotis Kanavos Apr 15 '16 at 07:49
The code works as a normal app, but when I start the app in the assigned access there is the error – Pascal Scholz Apr 15 '16 at 08:02
