Thunderbird hangs with hundreds of open tabs

I am trying to move my emails between Thunderbird from my old computer to my new one. As I was saving the emails from a folder, Thunderbird opened a tab for each of my emails (at least 400) and now when I try to open Thunderbird on my old computer, the program hangs and is unresponsive. Is there a way to restart the program without having all of the tabs open? I have tried safe mode both for windows and for Thunderbird but nothing seems to work!

Delete session.json from the profile folder, with TB closed. It stores the list of open tabs at last closing, and is automatically recreated when TB restarts.

C:\Users\username\AppData\Roaming\Thunderbird\Profiles\xxxxxxxx.default AppData is hidden by default.
