Authentication error with Yahoo mail

About 2 months ago I started getting errors accessing Yahoo mail in Thunderbird. I deleted the account and set up my IMAP according to the recommendations on the Yahoo site for third party apps. I have TB 102.4.2 64 bit on my HP desktop running Ubuntu 22.04. I have repeatedly, at least 20 times reconfigured to no avail. I have used TB with no problem for over 10 years. Back a few months ago I did set an application password for Yahoo as well.

I have looked at the solutions posted over and over again but no suggestions work.

Here are my settings: Incoming mail: Server Name: imap.mail.yahoo.com Port: 993 Connection Security: SSL/TLS Authentication Method: OAuth2 User Name: Myname@yahoo.com

Outgoing Mail: Server Name: smtp.mail.yahoo.com Port: 465 Connection Security: SSL/TLS Authentication Method: OAuth2 User Name: Myname@yahoo.com

What gives?

Thank you very much for all your help, even though we were not able to solve the problem. It is strange it works on my older PC and not the newer one.
