Very next and correct output lines that should appear, the ones that aren’t there, are following two:
found!
devname /dev/video0
Etc.
Therefore, as we all see where errors start, perhaps simple reinstall of here related package might help there, I think:
apt list millipixels -a
sudo apt autoremove
sudo dpkg -P millipixels
sudo apt update && sudo apt full-upgrade
sudo apt install millipixels
sudo apt autoremove
millipixels RET
