Opcache.php return an empty page

We are using PHP + FPM 8.2 + OPCache. In the past, we use https://www.repairrar.com/opcache.php to check its status. But today it returns an empty page. Although it shows an empty page, I view the page source and find its contents are about 3.3MB, but they are just not show in the browser. I tried Chrome and FireFox, but show empty contents.

I also write a small PHP file

<?php
    echo '<pre>' , var_dump(opcache_get_status(false)) , '</pre>';
?>

When visit https://www.repairrar.com/opcache-get-status.php, it shows the OpCache is enabled and performed properly:

  ["opcache_enabled"]=>
