Yahoo Thunderbird Setup Failure
Attempting to set up a yahoo email in thunderbird 140.9.0esr(64-bit). The goal is to have this set up on multiple workstations, so I've made the adjustments recommended per this article: https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo#w_please-check-the-following-before-asking-for-support
So, the toggle for mailnews.oauth.usePrivateBrowser is set to true, site/third-party cookies are always allowed (no exceptions), and the authentication method is set to OAuth2. Using the recommended server settings for yahoo: imap.mail.yahoo.com : 993 smtp.mail.yahoo.com : 465
I am able to set up the initial OAuth. The window pops up, I log in using the account password then put in the texted code, then the window closes and I get an email confirming the login. Hitting done within Thunderbird after this has it check the password again, and it fails: "Unable to log in at server. Probably wrong configuration, username or password."
This is on a fresh Windows 11 install/fresh Thunderbird install.

Also with a fresh antivirus is mu guess. The response comes to Thunderbird via the localhost adapter, many antivirus products block access to that because there was some malware 10 or 20 years ago that used it.
There is no third party antivirus on the PC, or any other typical OEM bloatware.
