Upgrading to 3.4.0.3, error related to PHPMailer

We tried to upgrade from 3.3.0.13 to 3.4.0.3 but got the following error: “[17-Oct-2023 05:32:27 UTC] PHP Fatal error: Uncaught Exception: Mailer driver isn’t specified in the application’s config in /home/…/public_html/lib/pkp/classes/core/PKPContainer.php:315.” Our host has tried to upgrade but recognized a code issue, which is beyond the scope of their service.

Thanks,
