Try deleting the parent.lock file from the profile folder, located by default in:

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

AppData is hidden by default in File Explorer.

Close TB, open a Run window (Windows key+R), type thunderbird.exe -p to open Profile Manager. Are there any profiles listed, and can you choose one and launch TB?
