I have a Samsung Galaxy Tab S5e (gts4lvwifi) using LineageOS 20.0 and certain apps (mostly apps for QR scanning) does not work. The official camera app works, but apps like QR scanners, cryptocurrency wallets, etc. Any app that uses a camera for scanning a QR code will just show a black screen an crash or display an error after 10 seconds or so when trying to use the camera in the app.

I have ensures these apps camera permissions are enabled and that camera access is enabled.
