Disappearing tabs in Thunderbird 91

Hi. I updated Thunderbird to the latest version (ver. 91 on Win10 64bit) and after few days, I noticed that all tabbed e-mails are missing after closing and opening Thunderbird again. I tried reinstalling Thunderbird - but it makes no difference.

Is it a bug in the latest version of Thunderbird that needs to be fix? Any solutions?

Regards Piotr

Chosen solution

Help/More Troubleshooting, Profile Folder, Open Folder, close TB, delete session.json, the file that stores the set of open tabs at last closing. Restart TB a few times and see if it retains the tabs.

@sfhowes Deleting session.json file helped. A few years ago I used deleting session.json when Thunderbird started to open in two or more windows, I didn't think to try this solution this time. Thx!
