Reinstall the macOS:
You need to reinstall the macOS. And to do that, reinstall the macOS. Nothing would be lost. It's just that misplaced items would be placed back to where they should be and corrupt system files would be replaced by clean files
Go Here: Reinstall macOS - Apple Support. Prior to the reinstallation, to prevent data loss, be sure to back up your Mac with Time Machine, so that you can have something to restore your Mac from, should anything happen after the reinstall.
This may a few hours(if you have never made a backup and/or if you have lots stored on your internal hard drive), so be certain you have the time to do so.
