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
—A SafeBoot Use safe mode on your Mac - Apple Support will sort many anomalies
Does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, third party system modifications and system accelerations are disabled.
Login and test. Reboot as normal and test. Caches get rebuilt automatically.
This test will tell you if third party interference; most* extensions etc are not loaded in safe boot mode.
