If you make a fresh Ubuntu user and log in as that, does it work for the user?

I created a new user then rebooted, the shortcut keys still don't work.

I switched display managers from lightdm to gdm and it fixed the issue

sudo systemctl status display-manager

sudo dpkg-reconfigure lightdm

systemctl status gdm.service

sudo apt install --reinstall ubuntu-session

reboot machine
