We are using unattended upgrades (security only), and we suspect that an automatic system update has installed a new Perl version that now causes these problems.
Have you ruled out the MariaDB update? That one seems the most
likely to have triggered this regression.

you seem to be running the prefork mpm so presumably only some of your
apache processes will have the libraries loaded by the actual Perl
application.)
