Hi,

There are some issues with Xcode 13.3.1, as per https://stackoverflow.com/questions/60015309/running-ios-apps-causes-runtime-error-for-frameworks-code-signature-invalid%C2%A0 the workaround is to use a paid apple developer account.

Could you please confirm that you are using a paid apple developer account and receiving this error?

Thank you.

Vuforia Engine Support

I'm having this same issue, is there any updates on this issue? 

The device i'm having issues on is this:

• Unity: 2019.2.12f1
• Vuforia: 8.5.9
• Xcode: 11.3.1
• Device: iPhone Xs Max
• iOS 13.3.1

Errors from xcode when deploying to this device: 

Start Vuforia Engine

Vuforia.VuforiaARController:StartVuforia(Boolean)

Vuforia.VuforiaARController:StartAfterInitializationCompleted()

System.Reflection.MonoMethod:Invoke(Object, BindingFlags, Binder, Object[], CultureInfo)

System.Delegate:DynamicInvokeImpl(Object[])

Vuforia.DelegateHelper:InvokeDelegate(Delegate, Object[])

The app stops here and never recovers.

However the same app, same build deploys to this:

• Device: iPhone X
• iOS: 13.2.3

I still get the error about `VideoBackgroundConfig with size of zero receives, skipping config step`, however it recovers and works as intended. this is the output following that error:

Hi @btsudios

Could you please provide us the entire xcode output after building the application on iOS 13.3? and would it be possible to provide us the project via pm?

In addition could you please confirm the Mac OS and Xcode version?

@NoovieARcade

Could you please confirm the Unity and Mac OS version you are seeing the behavior?

Thank you.

The crash on Mac when trying to edit the Vuforia Configuration is our only remaining issue at this point. We've downgraded Vuforia to 6.5.9 to resolve that problem.

Went into the console, and this is the bottom message from Vuforia:

ERROR/AR(764) VideoBackgroundConfig with screen size of zero received, skipping config step

Vuforia does successfully initialize before this point. Camera stays off.
