Extension C:/Program Files/Unity/Editor/Data/PlaybackEngines/VuforiaSupport/Managed/Android/Vuforia.UnityExtensions.dll was not registered, that means it relies on default UnityExtensions settings, please register extension and apply necessary settings for it in the callback.

Hi,
Could you please let me know with which version you get the error? is it a fresh install? or upgrade?
This could appear as a result of not activating Vuforia Reality Support in Unity’s XR Settings->…-> Player Settings.
Please give it a try.
Thank you.
