authentication problem yahoo mail cannot access OAuth dialog box

My family I are using Thunderbird 153.2. The affected accounts are all Yahoo POP accounts. IMAP accounts (Gmail) are not affected. Not sure if there was a Thunderbird update prior to this problem. Yesterday I saw the Yahoo OAuth dialog panel for no reason, didn't think too much about it and kept ignoring them thinking it was a glitch. That was a big mistake. I'm now having issues downloading emails from Yahoo. Previously when this happened a few years ago, I deleted cookies. That didn't work this time. I should have read support articles first. After reading support articles, I tried enabling cookies and allowing cookies from Yahoo, but I'm not sure which website to use (is it mail.yahoo.com?). I went into config editor and set mailnews.oauth.usePrivateBrowser to true. There are 4 Yahoo email addresses (I'll call them A, B, C, D). I am able to access all 4 yahoo accounts by webmail (email address and password). We use account A, B, and C the most. Account A seems to be the most stable however emails to A's inbox will show up in A, B, and C's inbox in Thunderbird. For some reason messages in A's inbox will go to trash in webmail as soon as Thunderbird checks and downloads emails from all accounts. Which is strange since I have always set A to leave messages on the server until I delete them. B's emails are not downloading to Thunderbird at all and are staying in the inbox. I am hoping to access the OAuth dialog box for each account to properly configure them but have been unsuccessful so far. It's been a stressful 24 hours. What should I do? Should I reset the passwords for all yahoo email accounts? Delete the Yahoo email accounts and add them back? Or should I uninstall Thunderbird and reinstall? Any suggestions are appreciated.
