Can't sign into iCloud after Window Bios update

Signing into iCloud error Windows 11

After updating the BIOS on my Dell XPS running Windows 11 Professional, I could not sign in to iCloud. Error message: "Verification Failed. To finish signing in to iCloud for Windows, you need a verification Code. Sign in to an Apple Device running IOS 16.2 or later... " An Apple tech remoted into my computer and tried several things before suggesting that I contact Microsoft. I contacted Microsoft and a tech remoted into my computer and tried several things before suggesting that I contact Apple. Both the Apple and Microsoft techs ruled out firewall and antivirus interference. I have uninstalled/reinstalled iCloud (numerous times), uninstalled/reinstalled Microsoft 365 (numerous times), and reinstalled Windows, and tried resetting and reinstalling iCloud from within the Windows 11 control panel. The problem started when I updated BIOS on the desktop. Of course, iCloud works fine from my Apple platforms. This is frustrating. Helpful suggestions appreciated.
