ICloud Drive File Sync Stuck on Initializing

I am using Windows 10 Pro, iCloud Drive v15.0.215. My iCloud drive will not complete the file sync.

I have manually closed all running applications in the Task Manager and have also verified the account permissions are set correctly.

Any advice on what may be the problem and how to solve it?

iCloud Photo and Passwords/Keychain sync work perfectly fine and are updated as of this posting, but the iCloud Drive files are not.
