Lost my settings after update

Just updated to 91.12.0 version and lost all my settings, accounts, filters and so on ... How can I restore them, or can I go back to previous version so I can do a backup and hopefully use it with the new version?

They may still be there. If Thunderbird starts with the email wizard, skip it, click the Home tab, right-click and select 'menu bar' and then click help>moretroubleshootinginformation, scroll down to profiles, click 'about:profiles' and see if your profile is listed.
