Vuforia AR not working iOS

[arfa123]

I have developing React Native app in which there is AR feature. The app working fine on Android but in iOS successfully run but AR is not working. I have run the same Unity project directly without RN integration and its working fine on my iPad but when I export this project to integrate in my React Native app, Vuforia camera opening but AR not working.

Unity: 2019.4.10f1
Vuforia: 9.4.6
React Native: 0.62.2

This is the log on XCode after rendering UnityView:

Apple actively discourages that, and all application-wide methods of changing status bar appearance are deprecated

I think the problem is due to this error:
Dataset handwash could not be loaded and cannot be activated.

Can anyone please help me how make possible to load vuforia dataset?
