If Not Booting All the Way...

A. Restore from a Backup:

Do you have a Time Machine Backup of your Mac that you created prior to this? If so, restore from it. If not, take this as a learning experience, knowing to always create a Time Machine backup of your Mac prior to making any major change to is (i.e. macOS upgrade), so that you can have something to restore your Mac from, should anything go wrong with the reinstall.

B. Boot into Safe Mode:

Hold Down the Shift Key upon boot. Once at the login screen, release shift. See if it all now works. In Safe Mode, only necessary items load (i.e. the caches), and new preferences are set aside.

If nothing above works, then...

C. Reinstall the macOS:

Nothing would be lost, it's just that sometimes changes are made to your system, and then then processes become corrupted, technically. When reinstalling, deleted files are reinstalled, and misplaced files are moved back to where they should be. Go Here: How to Reinstall macOS from macOS Recovery - Apple Support
