Cannot launch Elements, keeps asking for logins. All login credentials are correct.

I have no problem getting into my Adobe account in a web browser. In fact I was able to modify my account by adding a backup email address. But Photoshop Elements will not open. It says "Sign in required." I enter the correct email address. I enter the correct password. I know it is correct because I can get into my account online through the browser. But as soon as I have entered the password, it simply returns me, without explanation, to the screen saying

"Sign in required.
Please sign in with your Adobe ID.

I have tried renaming SLCache amd SLStore in the system library Application Support folder. No results.

MacOS Ventura 13.2.1, Adobe Photoshop Elements Editor 21.0, Safari 16.3.

Resolved. It was Avast antivirus getting in the way of some kind of activation dialog. Disabling Avast... and finding the activation key that replaced the original one when the original one was revoked... solved the problem. Adobe Support was patient and great.
