10.3.38-MariaDB-log-cll-lve: The libmysqlclient driver version 3.1.20 is less than the minimum required version.

On certain hosting environments you might get the following error when upgrading your Drupal installation for example to 9.4.5:

"10.3.38-MariaDB-log-cll-lve The libmysqlclient driver version 3.1.20 is less than the minimum required version. Upgrade to libmysqlclient version 5.5.3 or up, or alternatively switch mysql drivers to MySQLnd version 5.0.9 or up."

The solution to that problem is pretty simple:

1. Login to your cPanel or similar
2. Select the "Select PHP Version" icon or similar
3. Deselect both the "mysqli" and "mysqlnd" options
4. Select "nd_pdo_mysql"; then "mysqlnd" will be turned back on automatically
