I recently updated to Thunderbird 140.0esr. Since updating, I have been unable to receive my emails. I can send emails, but I am unable to receive any new emails. The two email addresses that are not working are Gmail addresses. One of them has two-step authentication. In the previous version of Thunderbird, I was using OAuth2 authentication method, and it was working fine. I tried disabling the firewall and antivirus software. The configuration should, I assume, be the same. I can access my emails in the GMail application. However, I cannot open them in Thunderbird.
