When I ran the command `php bin/magento s:s:d -f` while upgrading Magento from 2.4.2 to 2.4.4, I get the following error.

`PHP Fatal error: Cannot use ::class with dynamic class name in /home/magento/web/magento2.perfectmakeupmirrors.com/public_html/vendor/laminas/laminas-mail/src/Message.php on line 394`
