What is the problem?
Using MJPG causes webcam/snapshot and webcam/stream to just return "Server Error". Using YUYV does work, but is stuck at 1080 (which is all that the device reports to support in that format).

What did you already try to solve it?
I tried to update with
sudo apt update
sudo apt full-upgrade
Have you tried running in safe mode?
I am not able to get it working even at terminal, regardless of OctoPrint.
