I updated Thunderbird on my MBP running OS 12.6 to the latest version last week 102.3.3. Since then, it crashes at launch every time I open it. I, perhaps unwisely, then uninstalled it and downloaded the beta version (106.5) , hoping that it was just a bug in 102.3.3. and would resolve. No such luck. It also crashes on launch every time, after showing me briefly the folders pane on the left. Moreover, I can't go back to a previous version since it tells me that my profile has been updated by a newer version. I would really like to get my profile loaded again, with my four email accounts and years of stored messages. Can anyone help?
