After silent update to Windows (11) version 128.2.0esr of Thunderbird all account information was lost. After I entered all credentials again Thunderbird confirmed that account data is correct and showed absolutely empty email folders. I tried to import from existing profile ( which I suppose update procedure should do automatically) but this did not change the result. The mail access method I use is IMAP. I can verifty that my emails are present on server via web interface.

This is extremely frustrating
