Hello, i'm using Thunderbird for almost 16 years (and therefore i have a huge email database wich in definitely dont want to loose). Now i have a unfortunately problem: Facts: - PC with sufficient RAM, Windows 10 with all updates - latest version of Thunderbird (102.3.0) - different Emailaccounts (gmx, gmail) - no Antivirus software, only buid-in Windows firewall Thundebird (wich i really appreciate) updated to 102.3.0 (while i was opening the browser manually). So i and Thunderbird opened the browser at the same time. No clue whether this is the reason for: Thunderbird now crashes every time when i open it. It does nothing but as soon i click into the thunderbird window it says "thunderbird doesn't react" (wich is true, i waitet one night ;-( I tried to: - copy back different backups of the profile-folder (one week old, another approx one month old) wich were backuped BEFORE the automated update to 102.3 - uninstall and reinstall current version von thunderbird - install some older versions of Thunderbird (they were always claiming, that the profile-files were modified by an newer version of thunderbird and they can't read them) - tried the current stand-alone version - created new profiels with the above described versions of Thunderbird and then copying the backup profile files into that - manually reduce the inbox-file in size (removing the mails of approx. the last 2 weeks) - removing all *.msf-Files bevore starting Thunderbird - removing the global-messages-db.sqlite bevore starting Thunderbird Everything with no effort. Thunderbird frezes everytime. I will spend 100 € (!!!) for a hint wich makes my Thunderbird working again, no joke!!! Regards Stephan
