    When I want to add an AR Debug Menu with AR Foundation 5.0.0 Pre 13 or 5.0.2 I get the following error:

    NullReferenceException: Object reference not set to an instance of an object
    UnityEditor.Undo.RegisterCreatedObjectUndo (UnityEngine.Object objectToUndo, System.String name) (at <68dc13de18804097a5f386c11cbbb64f>:0)
    UnityEditor.XR.ARFoundation.SceneUtils.CreateARDebugMenu () (at Library/PackageCache/com.unity.xr.arfoundation@5.0.2/Editor/ARFoundation/SceneUtils.cs:81)
    UnityEditor.GenericMenu:CatchMenu(Object, String[], Int32)

    In SceneUtils.cs it can't find the prefab defined on line 21:

    Code (CSharp):
    1. static readonly string k_DebugMenuPrefab = "Packages/com.unity.xr.arfoundation/Prefabs/DebugMenu.prefab";

    In the meantime as a workaround you can drag and drop the prefab from its location at 
    Packages/com.unity.xr.arfoundation/Assets/Prefabs/DebugMenu.prefab
