Failed update to 91.6.1- thunderbird completely unresponsive

My thunderbird installation updated itself to 91.6.1 and now only presents with the basic menu bars and screen dividers. If I try Tools-Preferences, nothing happens. Same with Tools-Accounts. Help-About works . In that screen, it says I an using 91.6.1 64-bit, then underneath it says "Restart to update Thunderbird". My calendar has also disappeared. I have restarted Thunderbird several times with no change, rebooting the machine also makes no difference. System is Win10 with all updates. The error console works, but unfortunately there is only a time-stamp, no date, so I don't when the error messages are from.

Any help to get it working again would be appreciated. Ken.

Problem solved Dave- I uninstalled thunderbird again, deleted the whole directory, then went through the registry & deleted everything I could that referred to Thunderbird. Then rebooted, reinstalled t'bird- same problem. Using the /P option (and starting as admin) I went through each of the profiles the manager presented, all had the same problem. I then found a back-up profile which worked, so I am running with that now. I don't seem to have lost much which is good. Don't know what caused the problem- why a failed upgrade would screw up the profiles I don't know- but hey, with your help it's working again- thanks. Ken.

I suggest downloading a copy from thunderbird dot net and installing over the current version. Somehow, the update got compromised.

Thanks David, sadly that didn't solve the problem. I tried going back to 91.6.0 and 96.5.1 but that didn't change anything. Next, I uninstalled thunderbird and re-installed 91.6.0 which was the last working version- no change. Then I uninstalled and then deleted everything left in the Mozilla folder, then re-installed 91.6.0, still no change. Oh, and after each uninstall, a reboot. Next, I started it with the -P option, and tried the various profiles on offer. When I tried the default profiles, it wouldn't start at all, saying it couldn't find a valid profile. When I tried my own profile (on my NAS box), it started but with all the various panes blank and most menu items not usable. Then I tried the same things, each time starting as admin- no change.

I've now tried everything I can think of and am completely out of ideas.

If you're comfortable with the registry, doing an uninstall and then doing a registry search for Thunderbird may let you remove some extraneous keys. But go carefully there. I've done it routinely, but I'm hesitant to advise others to do that. Something seems corrupt, but I don't know what. Will it start to the email wizard? That would be a good place to start, if possible.
