Have you tried the solution here?  It works for me but isn't ideal since the problem is with Avast itself.

You just add as exceptions in Avast: 'aus.thunderbird.net' and also 'www.thunderbird.net'

Yes, that's exactly what I've done.  I'm with you though... I'd like to see the actual issue addressed.

More posts on Mozilla forum about the Avast update problem.  Apparently AVG is also doing this:

https://support.mozilla.org/en-US/questions/1388972#answer-1535689
https://support.mozilla.org/en-US/questions/1384853
https://support.mozilla.org/en-US/questions/1387580
https://support.mozilla.org/en-US/questions/1390566
https://support.mozilla.org/en-US/questions/1389993
https://support.mozilla.org/en-US/questions/1391097

Seems either (1) adding Thunderbird update server exclusions to Avast or (2) disabling QUIC/HTTP3 scanning in Web Shield solves the issue, however (2) does not work for me.

Avast staff, any progress on this?  It was supposed to be fixed in the last beta but I can confirm after the latest update the issue still exists.
