AIOWPS Database Security : Manual Backup fails

I would like to change all of the WP database’s table prefixes so I wanted to back up the database first. I tried that using AIOWPS : Database Security : Manual Backup : Create DB Backup Now. It fails:

Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

In this case, WordPress caught an error with one of your plugins, All In One WP Security.

Error Details
=============
An error of type E_ERROR was caused in line 77 of the file /home/<site-folder>/public_html/wp-content/plugins/all-in-one-wp-security-and-firewall/classes/wp-security-backup.php. Error message: Maximum execution time of 30 seconds exceeded

I am hosting this site in WHM/cPanel. I am the server administrator. I recently ran a security scan using WHM’s WordPress Tookit and applied the following suggestions:

Restrict access to files and directories
Configure security keys
Block directory browsing
Forbid execution of PHP scripts in the wp-includes directory
Forbid execution of PHP scripts in the wp-contents/uploads directory
Block unauthorized access to wp-config.php
Disable scripts concatenation for WordPress admin panel
Turn off pingbacks
Disab le PHP execution in cache directories
Disable file editing in WordPress Dashboard
Enable bot protection
Block access to sensitive files
Block access to potentially sensitive files
Block access to .htaccess and .htpasswd
Block author scans
Change default administrator’s username

What could be going on here? Could this be the consequence of one (more more?) of the above changes?

Here are some of my specs:
WordPress version 5.8.2
Current plugin: All In One WP Security (version 4.4.9)
PHP version 7.4.23

Thanks for all help and/or advice on this.
