App freeze at launch

April 17, 2018 - 8:15am #1

I've been working on integrating Vuforia into a HoloLens training application.

I've downloaded the sample scene, brought in some of the content as a test, I can get Vuforia working using the sample scene as a base.

When I try to implement Vuforia on my main unity project, it causes the application to hang as soon as I launch it. As soon as I place the application window on HoloLens, I get a zzz icon, and nothing happens.

I even removed all Vuforia objects (ARCamera, image targets, etc) from the scene, but just having the Vuforia libraries in the project is causing the app to hang on launch.

Anyone have any ideas on the cause?

Both the sample that worked, and the project that didn't are using 2017.3.1f1 version of Unity.

Hello mwitkamp,

As mentioned in the HoloLens samples download section on this page: https://developer.vuforia.com/downloads/beta, please use Unity 2017.3.1p1 or later when developing for HoloLens as there is an issue Unity has fixed for HoloLens starting with this version.
