Hello Minnesota Frank.
Welcome to Microsoft Community.
Regarding to your information I assume that you can't clean the cookies with the feature "Clear browsing data on close".
Based on the conversation history and my knowledge, it appears that you have tried almost all troubleshooting steps related to
Microsoft Edge. Since we cannot reproduce the issue you are experiencing, it is possible that this is a problem specific to your user account.
First, you can try creating a new profile in Microsoft Edge and see if the issue persists.
edge://settings/profiles
If the problem still occurs in the new profile, I recommend trying the Microsoft Edge Canary version. If the issue does not occur in
the Canary version, it suggests that the problem may have been caused by a recent update to the stable version of Edge.
In this case, you can continue using the Canary version and wait for the official Edge update to address the problem.

However, if the issue persists even in the new profile and the Canary version, I suggest providing feedback to the Microsoft Edge team
about this issue by pressing Alt+Shift+I in Edge.
In the meantime, you can try using the InPrivate mode (Ctrl+Shift+N) or disable the cookies as a temporary workaround until
they fix the issue.

If there is anything not clear, please do not hesitate to let me know.
