No cameras available

I am facing the same issues. I have seen it in a fresh install of Jetpack 6.2, and on Jetpack 6.1 after running:

sudo apt update
sudo apt upgrade

Here is the error message:

nvargus_nvraw --lps

I verified that cameras worked on Jetpack 6.1 before running the update command, so I don’t think it is HW related.
