Unfortunately I didn't capture the full error last night, and my only Drupal site is already updated so I can't currently trigger it again, but if you search for "drush Unknown archive format." you'll find several other people reporting switching back to php 7.3 fixed it. Taking #540552 and #570228 into account, and php 7.3 no longer being in tree, it's probably best to remove drush entirely.
It looks like php-7.4 uses application/gzip for the *.gz mime type, while drush is expecting application/x-gzip. I will fix that in an -r4, since I need to hack in some more php-8.0 support as well.
