Endless loop of the function in PHP code caused this error.

Check whether your PHP-FPM and PHP versions match. Make sure there is a (correct) PHP-FPM configuration corresponding to your PHP and PHP-FPM version, respectively.

PHP-FPM (config in /etc/php/7.0/fpm) and PHP versions may have gotten out of sync while updating. Updated PHP (/etc/php/7.3/) may cause apache child segfaults because of missing PHP-FPM configuration in /etc/php/7.3/.
