PHPMailer not working in localhost WAMP anymore - php

Question

Please help me out here I have tried possible solutions from former threads but it is not working.
My PHPMailer was working fine in localhost WAMP up until yesterday."SMTP() connection failed" There were no errors in my code, my "extension=php_openssl.dll" is uncommented in the php.ini file. I used port 587 and I even tried 465 but it still doesn't work anymore. My GMAIL allows lesser apps access. No typo errors but then all of a sudden i saw an error in my VScode "intelephense undefined type PHPMailer error 1009" and it highlights lines $mail = new PHPMailer(true); and two more instances of PHPMailer. 3 red lines of that error message in total.
<?php

$email = $_POST['adm_email'];
$pword = $_POST['adm_pass'];
$tel = $_POST['adm_tel'];
$house = $_POST['adm_house'];
// instantiating and passing 'true' enables exceptions
$mail = new PHPMailer(true);

$_SESSION['time'] = $timestamp;

} else {

}
} catch (Exception $e) {

}
}
