Hi there.
I figured out, that after removing the language packets
thunderbird-locale-en 1:78.3.3+build1-0ubuntu0.20.10.1 thunderbird-locale-en-gb thunderbird-locale-de
installed from this source http://ppa.launchpad.net/ubuntu-mozilla-security/ppa/ubuntu/
and reinstalling the 1:78.3.2+build1-0ubuntu1 packets from the official Source,
fixed the problem in my case. maybe it helps?!
