Yahoo AT&T Mail has locked me out of my email account after the Thunderbird Oauth2 change. (140.8.1esr)

For years I have had 4 email addresses using Thunderbird to access email from Yahoo AT&T currently.com email (@att.net) using Oauth2. In early March, two of the email addresses stop working. For one of the email addresses I was able to login to Yahoo mail using the User ID and Access ID and establish a new Secure Mail Key. I then went back to Thunderbird and reentered the email address with the new Secure Mail Key and was able to reestablish connection. For the second email address, Yahoo mail locked me out. I have tried to contact Yahoo support for 2 weeks by filling out their forms and have not received a response. Also I do not have a Recovery Email address. Any suggestions ?

Where specifically (what url/web link) do you get the idea that 140.8.1esr has changes for yahoo or oauth2 authentication? Thunderbird has only changed for 148 release.
