Blank Screen- Microsoft Hololens emulater

I am new to MRTK & Unity development & need help to complete one POC.

To learn, I started with Hololens Far & Near cube example in Unity & wanted to test it in Hololens Emulator.

  1. Created a Scene in Unity with two cubes.
  2. Build & RUn in Unity with Target device as Holones for Windows Universal Platform.
  3. Ran sln file in visual studio.
  4. Hololens Emulator launched.

till here it's all good. But after this Problem starts.

  1. Hololens is Stuck with a Black screen. Black Screen with hand
  2. Breakpoint is triggered VS 2019. Breakpoint
  3. When clicking on COntinue, Hololens shows 4 balls rotating. 4 balls rotating

I have no idea what happened to Cubes? & what is the meaning of this screen?

Regards, Mayank Pande

I have tried to reproduce this issue.

  • HoloLens is stuck with a black screen. -> In some projects this can be reproduced. The project is running with debugger with visual studio, HoloLens only shows 2 hand ray casts. It happens on both Emulator and physical devices, and this can be caused by corrupted MRTK profile. I create a new project and import the latest packages via Mixed Reality Feature Tools, then migrate assets to the new project to solve this issue.
  • Breakpoint is triggered VS 2019 -> Is the breakpoint expected? Otherwise, you may try to turn off the first chance exception in VS 2019.
  • HoloLens shows 4 balls rotating -> it is expected behavior when opening a project in Emulator. This animation indicates the resources are being loaded and it follows with Unity Splash screen, then the main scene of your Unity project.
