4k camera stopped working

ROCK 5 Series 5B/5B+

Hello, trying to work with 4k radxa camera, and stumbled upon some problem.
Tried this guide https://wiki.radxa.com/Rock5/hardware/camera/#Software_configurationRock5/hardware/camera/ - Radxa Wikihttps://wiki.radxa.com/Rock5/hardware/camera/#Software_configuration
and it worked, but after working with other stuff I tried to enable it again and it failed with this log:

You may need to run with sudo.

Copy & Paste the text here (not image).

rock@rock-5b:~$ sudo ls -la /dev/video-camera0
lrwxrwxrwx 1 root root 7 Mar 8 11:16 /dev/video-camera0 -> video11

I think you have a udev rule or you installed a deprecated package over a working one.

Try this:

sudo v4l2-ctl --device /dev/video-camera0 --stream-mmap=4 --stream-count=1 --stream-skip=150 --set-fmt-video=width=1920,height=1080,pixelformat=NV12

and this
sudo v4l2-ctl --device /dev/video11 --stream-mmap=4 --stream-count=1 --stream-skip=150 --set-fmt-video=width=1920,height=1080,pixelformat=NV12

If this does not work i can only suggest removing the packages related to the camera and installing the latest one.

What package do I need to reinstall, I tried new distro installation, and still not working.
The output of commands are following:

rock@rock-5b:~$ sudo v4l2-ctl —device /dev/video-camera0 —stream-mmap=4 —stream-count=1 —stream-skip=150 —set-fmt-video=width=1920,height=1080,pixelformat=NV12
VIDIOC_STREAMON returned -1 (Operation not permitted)
rock@rock-5b:~$ sudo v4l2-ctl —device /dev/video11 —stream-mmap=4 —stream-count=1 —stream-skip=150 —set-fmt-video=width=1920,height=1080,pixelformat=NV12
VIDIOC_STREAMON returned -1 (Operation not permitted)
rock@rock-5b:~$ sudo su

Triple check the camera cable and the contacts.
