Black Scrreen after Splash Screen after deploy on HoloLens

Hi.
I am working on a virtual assistant for the Hololens. For that, I need Newtonsoft(I put Newtonsoft.JSON.dll in the Assets/Plugin folder of Unity. I use for API connections. In the Unity Editor, everything works fine. I have a problem and could not find a solution for it. Last week everything worked fine with the build in Visual Studio.

I think I installed some components in visual studio but I am not sure. In Visual Studio I get a black screen after splash screen ([99535-logfile.txt|99535]). I searched a lot, but I could not find any solution. Do you have experienced something similar?
I tried the following things:

  • Check that “automatically search for missing nugget packages during build is enabled”
  • In emulator use, desktop acceleration graphics is disabled in emulator.
  • Clone an even older working solution but same problem (black screen)

For the development I use:

  • Unity 2017.1.0.0f3
  • Visual Studio Enterprise 2017 15.2

I hope you can help me
Cheers Fabian

I solved the problem. With Unity 5.6 everything works fine and I don´t get a black screen.
