NullPointerException com.google.android.cameraview.Camera2 in collectCameraInfo

Summary

Using the latest version of expo-camera, we have bug reports from Redmi Note 9 Pro users for whom our app crashes when they try to take pictures.

Here is the stacktrace we get (from Sentry):

java.lang.NullPointerException: Attempt to invoke interface method 'java.lang.Object java.util.SortedSet.last()' on a null object reference

We’re using Camera2 API (through useCamera2Api prop), but we were unable to reproduce on our side as we don’t have access to this kind of Android device.

Also happening on Redmi 7A.

An ugly workaround is wrapping the crashed code and switching to cameraX on exception.
