'$_SESSION array is empty after redirection - Wordpress

I have a WordPress page template themename/template-payment.php

    <?php
    /**
    * Template Name: payment
    */
    session_start();
    
    ?>
    <!doctype html>
    <html>
    <head>
    </head>
    <body>
    <form action="/stripe_payment/charge.php" method="post" id="payment-form">
    <!-- form fileds and submit button-->
    </form>
    </body>
    </html>
?>

I have created a page using this template. page url : https://www.sample.com/payment When I submit a form using this form the data post to /stripe_payment/charge.php file. stripe_payment folder contain in the root folder of the website.

the charge.php file:

<?php
session_start();
//do the payment things
//store data in php sessions
$_SESSION['paid_amount'] = $paid_amount;
$_SESSION['invoice'] = $invoice;
$_SESSION['payment_status'] = 1 ;
header('Location: https://'.$_SERVER['SERVER_NAME'].'/payment-result/' );
?>

after payment process I store a set of data in php sessions and redirect to a result page.

url: https://www.sample.com/payment-result

but when I try to print the session data the session array show as empty

<?php
/**
* Template Name: payment-result
*/
 
session_start();

print_r($_SESSION);// empty??

die();

?>

But if I redirect to a php file after payment I can see the session array has values.

header('Location: https://'.$_SERVER['SERVER_NAME'].'/tes.php' );//session not empty

But if I redirect to a WordPress url, the session array show as empty.

header('Location: https://'.$_SERVER['SERVER_NAME'].'/payment-result/' );// session empty

I think there should be some issue with WordPress, But could not catch the issue. Can anyone help?
