Hi DocEdBrown-
I'm Kevin B. Windows user like you. I do apologize for the inconvenience, let me help you sort things out.
Is this a new computer or Is there any changes happened on your device that might trigger the concern?
Kindly check if you are on a correct time zone. It could be a account problem, kindly try to create a new user profile on your Windows:

If the issue persist you may perform in place repair on your machine:
In-place repair/upgrade or repair reinstall is a process of re-installing Windows without touching any of your applications or personal files. In this way if there's any data corruption, damaged system files or missing system files on your computer, this repair will fix or repair them.
To start we need to download an ISO file of Windows 10 and save it to your computer. Please follow the instruction on the link below to create an ISO file

After the ISO is created, follow the instructions on the link below created by PaulSey, Microsoft Agent, on how to perform repair install on your computer.

This process will take some time to complete so you need to be very patient in waiting until the process completes. Once done , restart your computer and check if the issue is resolved.
Hope this will help and have a blessed day!
Thanks,
Kevin B.
