New Laptop. Windows 11. Bitdefender protection. Installed Thunderbird and a first gmail account on new Laptop, all OK. Attempting to instal a second, different gmail account I get the following message from Google: 

"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."

No problem having installing the 2nd gmail account in my internet browser on new laptop after continued failures to instal in Thunderbird. NB I have both gmail accounts previously (and easily) installed and working in Thunderbird on PC, old laptop, phone. Issue does not make sense. Does anyone have a solution please.
