Problem after upgrade to WordPress 5.2

After the upgrade, I am receiving notification that WordPress has caught an error with my Divi theme. The page with the error is https://www.swarmnetics.com/wp-login.php.

Below is the error message from WordPress:

An error of type E_ERROR was caused in line 212 of the file /home/swarmnet/public_html/wp-content/themes/Divi/functions.php. Error message: Uncaught Error: Call to undefined function et_load_unminified_scripts() in /home/swarmnet/public_html/wp-content/themes/Divi/functions.php:212

Divi support has reviewed by site configuration and cannot find any issues. They suspect that the issue might be with WP Cerber as I am using a custom login URL configured through the plugin.

Please advise.
