Weird Log-in Issue

Awhile back, I got this pop-up on my mac laptop

The apps themselves still worked, so I wasn't terribly concerned, but the popup is annoying. So today, I start investigating fixing it. 

HOWEVER...
for some strange reason, the log-in screens for software download installs don't accept my Adobe log-in credentials. I log into the Adobe site using an email address. Can change the password easily. Have the adobe authenticator working as intended. But my NAME is in the login block on the software activation block. (I've deleted most of my name as that seems prudent.)

This login screen won't accept the adobe password associated with my email address, and changing my name to the email address renders the same "uh-uh" result. I did find that in 2021, I connected my Adobe and Apple accounts, and the Apple stuff comes up with my name. So I disconnected the two accounts. 

Sadly, no joy. I'm at a loss.

It doesn't make any sense to me. I did screenshot the CC install data from "finder", and I'm assuming the September date is the last successful update, in case that is helpful info.
