Recurring iCloud verification error on Windows 11 with multiple duplicate devices

I am encountering a recurring verification error when attempting to sign in to iCloud on my Windows 11 computer. I am confident that my password is correct because entering an incorrect one results in a different error message:

Incorrect password: "Verification Failed: Your Apple Account or password is incorrect."

Correct password: "Verification Failed: This action could not be completed. Please try again later."

Additionally, when I access my Apple account's device management page through a browser, I notice that my Windows 11 device appears nine times, under the same name i see iPhone once but windows 8 times.

I have already tried signing out of iCloud and signing back in, but the issue persists but only on the iCloud program. If I use a browser, it works fine. Could you please provide guidance on resolving this?

Thank you for your time and assistance.
