Please upgrade to be compatible with Thunderbird 141. In the meantime I've worked around the incompatibility by downgrading to Thunderbird 140 (download it from https://releases.mozilla.org/pub/thunderbird/releases/140.0/), install it and then delete or backup the compatibility.ini file from your profile directory to bypass the version compatibility check which prevents you from downgrading (to play it safe make a copy of your profile directory just in case there is an issue).
