You upgraded to W11 or you clean installed W11? If you upgraded, was TB on the computer before the upgrade? If there seems to be a problem following an OS upgrade, it is more likely to be the upgrade. Check that you are running the up-to-date version of TB and upgrade as necessary (128.5.2esr). It might be best to make a new email account after you've accessed your email provider to get the current settings but, first, prevent TB from automatically downloading emails.
