I have just upgraded my project from Unity 2018.2.5f1 and Vuforia 7.2.23 to Unity 2018.3.0f2 and Vuforia 7.5.26.
The upgrade went fine and my main scene works as expected in the editor, the problem is when I deploy and run on HoloLens. Before, once I started the app for the first time, the system used to prompt me the camera permission dialog; now it stopped prompting that and Vuforia does not start at all (I guess that the webcam cannot be accessed). Even if I give the app access to the camera through the settings, Vuforia still cannot start.
Anyone having the same issue? Any ideas?
