Hi GraniteStateColin,
I appreciate the update and the additional info. My apologies also if the methods you have tried did not work for you. Let's perform a Clean boot. Putting your system in a Clean Boot state helps in identifying if any third-party applications or startup items are causing the issue. Kindly follow the steps from the Microsoft article mentioned below to perform a Clean Boot.

Once done, reboot, check and observe. It was a good thing that you sent your concern also thru the Feedback Hub app. Hopefully, Microsoft would take notice and action.
IMPORTANT NOTE: In the article, refer to the section "Reset the computer to start normally after clean boot troubleshooting" to reset the computer to start again as normal after troubleshooting.
Have a good week ahead.
