Wallch not working since Plasma 6

I use KDE neon 6.0 (the KDE OS, based on Ubuntu) and I have recently updated to Plasma 6. Since then I've noticed that the desktop wallpaper was not updating and I searched for information about Variety not working on Plasma 6. After not finding I anything I've noticed that Wallch wasn't running because it fails to start giving the error. app-wallch@autostart.service: Failed with result 'exit-code'. app-wallch@autostart.service: Main process exited, code=exited, status=127/n/a /usr/bin/bash: line 1: /usr/bin/wallch: No such file or directory After that I was suggested to check systemctl And I found this that I'm not sure if it's related to the issue ● apparmor.service loaded failed failed Load AppArmor profiles
