Scripts not executing in UWP

Unity 2017.2.0b8 (also tried 2017.1)
Visual Studio 2017 15.3.2
Backend: .NET. (cannot compile with IL2CPP)

HoloLens/UWP project builds from Unity without errors. The Visual Studio project created from Unity also builds and deploys without errors. However, any of the scripts attached to GameObjects do not initialize/execute. The scripts do execute in the Editor.

 

I've tried wiping and recreating all temp files (Library, Packages, ProjectSettings, Visual Studio files, etc) on my project. I just verified with an empty project, same thing.

Actually, I just noticed that it doesn't load anything (not even any assets). The HoloLens window turns black/transparent, and disappears. Normally, when you do the "bloom" on HoloLens, the window is white.

CPU and Memory usage also flattens...which means its just dead and not doing anything.

 

In the Editor, it runs fine. If I run/deploy the UWP project to my local Windows 10 machine, it crashes with unhandled win32 exception.

 

Difficult to get the call stack. I get the following error in debug mode. It doesnt help even if click OK launch a new debugger.

I get the same thing and have been stuck on this for a few days now. Would be great to hear what the solution is.

 

Those are the exceptions that get thrown when I debug it in HoloLens....no unhandled exception in HoloLens. That only exists if I run it on a Windows 10 PC. That unhandled error seems to related to Spatial Map...which PC obviously is missing.

On HoloLens, it keeps running. Here's the last of the lines from VS output:

There is no stuff happening. I turned the Unity splash back on, and even that doesn't show. So its even before that. Its hard to know when it crashes. But here is the HoloLens call stack at the last exception (Microsoft C++ exception: wil::ResultException):

Looks like this a known issue. From 2017.2.0b9 release notes:

"XR: Windows Mixed Reality usage on b7 results in hangs and black screens at start-up. This has been fixed in b8 for VR HMDs, but is still an issue for HoloLens"

 

Try update VS to 15.3.2 -> 15.3.3, it works here on my PC (with Unity 2017.1.0p5).

 

Any updates about "You are calling into spatial mapping system too early!"? I get the same error.

What a mess "developing" for hololens!

 

I have same problem
