Microsoft Store says "You need administrator privileges to pause updates" even though I am an administrator

I am using Windows 10 Pro, version 22H2, OS Build 19045.7548.

In Microsoft Store, I am trying to turn off App updates from:

Microsoft Store → Settings → App updates

When I try to turn it off, Microsoft Store displays:

Can't pause updates You need administrator privileges to pause updates on this device.

However, my Windows account is an Administrator. I have also previously been able to turn off Microsoft Store app updates on this same PC, so this behavior appears to have changed recently.

I have already tried the following:

Confirmed my account is an Administrator using netplwiz.

Ran wsreset.exe to reset the Microsoft Store cache.

Restarted the computer.

Checked Local Group Policy Editor → Computer Configuration → Administrative Templates → Windows Components → Store.

The policy "Turn off Automatic Download and Install of updates" is currently Not Configured.

Other Store-related policies are also Not Configured.

Despite this, Microsoft Store still says that I need administrator privileges when I try to disable App updates.

Why is Microsoft Store incorrectly detecting that I don't have administrator privileges, and how can I restore the ability to turn App updates off from Microsoft Store Settings?

I would prefer to fix the underlying issue rather than using Group Policy to disable Store updates.
