Had to reinstall Thunderbird from scratch. Used version 115.5 but it would not connect to my gmail account. Had to drop back to version 102.12.0 to get it to connect to gmail. Gmail response to 115.5 was something about malformed request. The error page from gmail show 400 as error code.

This sounds like something that would have been a temporary connection issue, not a bug in Thunderbird.
Anyway, when you do have a problem, it is best posted at https://support.mozilla.org/en-US/questions/new/thunderbird. Connect is really for discussion and ideas, not support problems.
