After upgrading from Windows 10, the Check for updates button appears greyed out and unresponsive.

 After upgrading my computer from Windows 10 to Windows 11, the "Check for updates" button in the Windows Update interface has remained greyed out and is completely unclickable. I have tried every method I could find online, such as running the Update Troubleshooter, resetting the Windows Update components, and checking service statuses, but the button is still disabled.
