Smart Mailboxes Missing with Ventura 13.2.1

Just discovered my (dozens of) Smart Mailboxes have vanished from Apple Mail after 13.2.1 Ventura update. Just finished with Apple Support: They “may have been deleted” and we can’t help you. More discussion at Apple Communities here.

Citizens: If you use Apple Mail and are now with Ventura 13.2.1 you may want to confirm your Smart Mailboxes are present and actually working. That is all.

Mine are all still there with 13.2.1
