Thanks for the report Matthias. Could you please run `apport-collect 1901568` to attach additional debug info to this bug? (this may require installing the transitional chromium-browser package if it isn't installed already).

Thanks for the additional data Matthias. Just a quick check: does the webcam work correctly in other WebRTC webapps, or is it the same everywhere?

I don't see anything related to snapd in the attached logs, the camera plug is connected and there are no denials related to camera access in the dmesg.txt (the other apparmor denials seem unrelated to camera interface). I'm closing this in snapd; please re-open if needed.
