icloud for windows keeps asking for password
I am using a Dell i7 laptop with fully-updated Windows 10 Home.
Computer runs antivirus and Malwarebytes.
I have been using iCloud for Windows on my device for years, BUT
For the last 48 hours, every time my computer awakes from sleep or is rebooted, I am asked for my iCloud for windows password and my two-factor authentication code.
I have uninstalled all Apple software and freshly reinstalled just iCloud for Windows, but the issue persists.
I spent an hour+ on the phone with Apple Support yesterday, but no solution yet, so I am turning to the Community for some ideas.
Thanks to all!
