Fatal error: Cannot use ::class with dynamic class name in /vendor/laminas/laminas-mail/src/Message.

I am trying to upgrade Magento 2.4.3 Adobe Cloud version to 2.4.4 and I was successfully update the composer.json with necessary changes. Also I was able to run the di:compile command successfully. Now when I am trying to access my website I am getting this error

Fatal error: Cannot use ::class with dynamic class name in /var/www/html/vendor/laminas/laminas-mail/src/Message.php on line 394

Does anyone faced same issue?

Same issue after upgrading from 2.4.4 to 2.4.5. Any solution is appreciated.

The problem connected to the PHP version in CLI (terminal). PHP version must be 8.X, but not 7.X. Error goes away if PHP version changed.
