access denied "persist.vendor.camera.privapp.list"

I'm doing following tutorial where you implement a TensorFlow Lite model in an android app: https://codelabs.developers.google.com/codelabs/recognize-flowers-with-tensorflow-on-android/#0

Everything works well except that following error messages shows up while testing the app and my model doesn't recognize the images.

Has somebody experienced this issue before? I'm testing the app with a Xiaomi Redmi Note 9 Pro.
