App-crash on HoloLens(1st. gen)-Emulator when enabling 'Spatial Awareness System' in MRTK 2.3

i recently set up required software for development for the Microsoft HoloLens(1st. gen) with the newest version of the HoloLens(1st. gen) emulator (followed the MRTK-Guide: https://microsoft.github.io/MixedRealityToolkit-Unity/Documentation/GettingStartedWithTheMRTK.html#get-the-latest-mrtk-unity-packages). I already tested some example scenes from the MRTK on the emulator and everything works as expected. However, when i test the SpatialAwarenessMeshDemo, the app starts within the emulator with the unity start-screen. Then the scene is visible but after 1-2s the scene disappears and exceptions are thrown. Visual Studio Log:

HoloLensTest.exe has triggered a breakpoint. 

After trying out with different scenes this only happens if i choose a profile in the MixedRealityToolki-object where 'Enable Spatial Awareness System' is enabled. I already tried cloning and modifing the DefaultHoloLens1ConfigurationProfile by enabling 'Enable Spatial Awareness System' and adding the 'SpatialObjectMeshObserver' to the Spatial Observer list. I double-checked my project-settings and the Unity-Package-Manager for the right settings.

Does someone has a clue about what the cause of this problem might be?

So i ironically found a solution for this just after posting the question: I stumbled about this https://github.com/Microsoft/MixedRealityToolkit-Unity/issues/3554 so i installed an older version of the HoloLens(1st. gen) emulator and everything works fine. Older versions: https://docs.microsoft.com/en-us/windows/mixed-reality/hololens-emulator-archive

version that worked for me: HoloLens Emulator build 10.0.17134.80
