Five things to Try:
A. Remove Login items:
See if any of these apps are a Login Item. If so, remove them as such and then restart the Mac, seeing if it/they no longer load(s) at login. Go Here: Change Users & Groups Login Items Preferences on Mac - Apple Support.
B. Scan your Mac for Malware:
Use MalwareBytes for Mac --- This is software that searches for malware/adware. So, scan with it and then remove what is found. Once removed, uninstall MalwareBytes for Mac. Then restart the Mac. Malwarebytes is made by longtime users of these forums, making it the onlySecurity Software reliable for Macs.
Downloads:
C. Single Out this User:
For temporary user, create a new administrator, seeing if you still get this error. If so, then it is an error in the macOS. If so, then it is an error with the current user. So, what you would do is trasnfereverything over to this new user, and then trash this current user.
D. Restore from a Backup:
Do you have a Time Machine Backup of your Mac that you created prior to this? If so, restore form 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 upgrade.
Or, as a last resort...
E. Reinstall the macOS:
Nothing would be deleted. It's just that items that have become corrupted or deleted, would be replaced or reinstalled back to where they should be. Go Here: How to reinstall macOS from macOS Recovery - Apple Support. Important: Be certain to create a backup of your Mac prior to all of this. That way, you can have something to restore from the Mac from, should anything go wrong with the reinstall. Once reinstalled, try this once more, seeing if you still get this error.
