Weird crash on Unity 5.5.3F1, UWP SDK 14393, HoloLens Windows 10.0.14393.1083
Hello, guys. Long time no ask.
I have finally obtained my own HoloLens and am experiencing a very weird crash deep in the Unity code. I do not use HoloToolkit for this demo, only plain and simple SpatialMappingCollider component. The scene is basically a camera, a very simple cursor and a SpatialMappingCollider (no renderer). The cursor on Update raycasts to spatial mapping and positions itself there.
Spatial mapping:
It works perfectly, but then, once in say 3 seconds, it simply throws the following exception:
Exception thrown: 'System.NullReferenceException' in UnityEngine.HoloLens.dll NullReferenceException: Object reference not set to an instance of an object. at UnityEngine.VR.WSA.SpatialMappingBase.ShouldRemainActiveWhileBeingRemoved(Surface surface) at UnityEngine.VR.WSA.SpatialMappingBase.OnRemoveSurface(SurfaceId surfaceId) at UnityEngine.VR.WSA.SpatialMappingBase.OnSurfaceChanged(SurfaceId surfaceId, SurfaceChange changeType, Bounds bounds, DateTime updateTime) at UnityEngine.VR.WSA.SurfaceObserver.InvokeSurfaceChangedEvent(SurfaceChangedDelegate onSurfaceChanged, Int32 surfaceId, SurfaceChange changeType, Bounds bounds, Int64 updateTime) at UnityEngine.VR.WSA.SurfaceObserver.$Invoke10(Int64 instance, Int64* args) at UnityEngine.Internal.$MethodUtility.InvokeMethod(Int64 instance, Int64* args, IntPtr method) (Filename: <Unknown> Line: 0)
I have:
- Windows 10 Pro
- Unity 5.5.3F1 (Build settings: Universal 10, HoloLens, D3D, 10.0.14393.0, Local Machine, Spatial Perception and Mic capabilities enabled)
- HoloLens Windows 10.0.14393.1083 (latest update)
Has anybody dealt with this nasty exceptions before?
Thank you for any hints!

For anybody experiencing the same crash. The solution is to make sure the camera has "MainCamera" tag.

Thanks! Your solution is very helpful! Although I am still confused about what this error does, because I don't see any difference in terms of performance/results.
