shows that Lightning is involved into the issue and maybe the root of it. But not Thunderbird itself. > I hadn't tried creating a fresh profile.

As written on the wiki page, quite most of such issues, like this report is about, are caused by outdated or somehow faulty AddOns or some user modified configuration. > There's still a problem though; my existing profile contains a lot of > information I don't want to lose or have to manually recreate, like > message filter rules and so on. These are more or less easy to migrate as these are just files. Message filter for example https://www.systutorials.com/how-to-export-and-import-message-filters-of-thunderbird/ Address books are also easy, just copy all *.mab files into the new profile, or export them within the UI But there are also some AddOns which can help with such tasks. https://addons.thunderbird.net/en-US/thunderbird/addon/importexporttools-ng/ -- Regards Carsten Schoenert
