Mac cannot connect to iCloud

This question was posted in June 2018 and none of the suggestions work for me. This problem started when I updated MacOS to 10.14.6.

A window keeps popping up which says "This Mac can't connect to iCloud because of a problem with <apple id>. Open iCloud preference to fix this problem". I open iCloud preference and enter the password to proceed and this message appears "An unknown error occurred" and the there is no end to the loop starting from the beginning! In the process, my mail boxes and iCloud drive files have disappeared.

I have gone through at least 30 discussions in various forums about the exact issue as mine. I have tried almost all the solutions suggested except probably formatting the Mac. I have tried the following:

1. Changed password

2. Signing out of iCloud on this mac does not happen as the same error shows after entering the password

3. Restarting and shutting down the Mac several times

Try setting up another admin user account to see if the same problem continues. Please post back on whether or not this worked. Also try the Safe Mode. Please post back on whether or not this worked.

If it works in the Safe Mode, try running this program when booted normally and then copy and paste the output in a reply. The program was created by Etresoft, a frequent contributor.

Do a backup, preferable 2 separate ones on 2 drives. Boot to the Recovery Volume (command - R on a restart). Run Disk Utility and select First Aid. Then re-install the OS.

Reinstall from macOS Recovery

OS X Recovery

I have the same problem as stated here. I tried setting up an additional/different admin account, with no success. I also tried going into safe mode with no success. It appears that the machine will not recognize my credentials although it always me to log in. Anything that requires Apple credentials does not work, including Safari, whereas Tor works with no problem!
