Verify you are maintaining an admin account for your current user account.

You can always force quit a shutdown by holding the power button/TouchID for ~6-10 sec.
Force Shut down your Mac.
Log out, sleep, wake, restart or shut down your Mac
Shut down or restart your Mac - Apple Support
then reboot as normal and compare your results...
