Migrating from a Windows 10 computer to a Windows 11 computer and many aspects are not working correctly
I'm migrating Thunderbird from my old Windows 10 computer to a new Windows 11 computer.
I've installed Thunderbird v115.12.2 and successfully moved all my accounts, emails, calendars, etc., to the new computer.
Several things are NOT working correctly, though:
1 - Settings will not open. Here is the message from the error console:
Error: No such tab mode: preferencesTab
openTab chrome://messenger/content/tabmail.js:758 openTab chrome://communicator/content/utilityOverlay.js:257 openPreferencesTab chrome://communicator/content/utilityOverlay.js:295 openOptionsDialog chrome://messenger/content/mailCore.js:628 oncommand chrome://messenger/content/messenger.xhtml:1

2 - Customize menu does not open
3 - The hamburger menu in the upper right corner does not open
4 - The spaces toolbar on the far left is missing
5 - Events and Tasks are missing from the menu
6 - My calendar is nowhere to be found - I can't find a way to access it (on my old computer, I clicked on the calendar icon in the spaces toolbar on the left side of the window)
Thunderbird on my old computer was also running v115.12.2 when I backed up the profile folder to move it.
I tried downgrading to Thunderbird v102. I had all of the same issues listed above PLUS all my accounts and emails disappeared. -- I've brought it back up to v115.12.2.
Could someone please help me get Thunderbird working correctly?

A bit off the wall, but where did you download your Thunderbird from? I have some bad feelings about the version offered in the Microsoft store. Mostly because it works in some sort of sandbox that is not explained anywhere clearly.
Weird. (my one word synopsis)
Did any of those things work before the profile migration? Where was your profile on the old machine Vs new? I would expect some variance in the user name in the appdata path, but is it on the same drive letter?
Everything worked (and still works) perfectly on the old computer (Windows 10).
Everything is identical on file location - c: drive - under identical computer "user" name.
