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)

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,
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.
