Camera not turning on with Vuforia 6.2

December 22, 2016 - 7:14am #1

Hello, 

I am reporting a bug that I have found using the current release of Vuforia (v 6.2). The camera does not turn on and the following is the bug report I caught from xCode. 

Exception in callback: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object

Hello hasnain687,

Are you running the sample apps? What device are you building to? Does Playmode work?

Thanks,
