Unity 3D: Not rendering camera when using Unity as library on Android Studio

I've successfully imported a project from unity to Android by importing the AAR. However my Camera feed is not rendering and the rest of the app functions properly.

I'm trying to integrate Mapbox AR Unity to my Android app. The app opens but camera does not. I'm getting this error code in my Android studio logcat on running the app:

Here's a Github issue link I raised but didn't get a good reply from Mapbox.
