Rear Facing Camera Not Working, Intro to Machine Learning

I am trying to do the Intro to Machine Learning series about image classification.

I have a Note 10+ and the app launches and works… except for the rear (main) camera. I know the phone is not listed as a compatible device with lookextension, but I ran the test and it worked fine.

However, when I launched the app after building it below, the selfie camera worked fine and the rear camera was black.

Personal Image Classifier

Any ideas?
