stuck in Thunderbird "restart to upgrade" doom loop and can no longer use it

For the past 3 days, I've been locked out of using Thunderbird email. When I try to open it, I get a "Your computer must be restarted to complete a previous upgrade of Thunderbird. Do you want to restart now ?" "Yes/No" option pop-up.

This is infuriating. After several hours, I'm still no closer to being able to use Thunderbird again.

If I choose to restart, nothing changes and I just get the doom loop pop-up again.

If I install uninstall (via Windows Control Panel), again I get stuck with the "Your computer must be restarted to complete a previous upgrade of Thunderbird. Do you want to restart now ?" message.

I can find no useful advice in the Thunderbird help and forums. It's recorded as a known issue. But no viable solutions found.

Using Windows 10. Looks like Thunderbird tried to update to 115.16.2 on 28-Oct-24 (not something I requested).

Please let me know how I can fix it.

And do something to fix this bug (which is a shocker).

Do you still have this issue if you restart your computer in safe mode with networking?

These reboots are to replace a file that is "locked" at the time of an upgrade. If other software, like your antivirus is the thing doing the "locking" then a reboot in safe mode will bypass that and the update can complete.
