First things first, sorry for my English.
I updated my POP-OS to version 22.04 and my camera stopped working.
When I open a camera application, most of the time, the led on the side of the camera flashes once, but the camera doesn't work.
This is part of the syslog file:
This is the camera (lsusb):

from xinput list-props 9
in udevadm info -a /dev/input/by-id/* only these lines seem to be related to the camera.
the driver modinfo uvcvideo :
v4l2-ctl --list-devices
This is my fault. Originally there were video0 and video1, but the response to the command was no different from this. So I tried to remove video0 and the system created these two new numbers.
sudo guvcview
I don't know a lot about Linux, and for this reason, I just inserted a lot of output that appears to be related, hoping for help.
