Using v128.2.0esr (64-bit) on Windows 10

Trying to add GMail, had no problem adding other email accounts. I follow the same process- enter creds and click save/continue. Thunderbird opens a new window for me to sign into GMail to complete the process. It results in a 404 error:

400. That’s an error.

The server cannot process the request because it is malformed. It should not be retried. That’s all we know.
