This is covered in the documentation and in many duplicate questions on here.

You are getting this error because you are sending using PHP’s built-in mail function (which is what PHPMailer uses by default), but you do not have a local mail server installed or configured. Install a mail server and it will be able to work.

Alternatively, use SMTP to connect to a remote mail server. See the many examples provided with PHPMailer for how to do that.

You have not included the PHPMailer class in your code.

Put this at the top of your code.

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'path/to/PHPMailer/src/Exception.php';
require 'path/to/PHPMailer/src/PHPMailer.php';
require 'path/to/PHPMailer/src/SMTP.php';

There is no need to use the autoloader for this method. Try it this way and see if it works. Then you can tinker around with the autoloader.
