Current problem with Mongodb_php extension

So I have a problem using the php mongodb extension and whenever trying to launch the application I get the following error message from the Browser:

Fatal error : Uncaught Error: Class “MongoDB\Driver\Manager” not found in /Applications/XAMPP/xamppfiles/htdocs/Project-hshl-2024-main/vendor/mongodb/mongodb/src/Client.php:117 Stack trace: #0 /Applications/XAMPP/xamppfiles/htdocs/Project-hshl-2024-main/login.php(8): MongoDB\Client->__construct(‘mongodb+srv://M…’) #1 {main} thrown in /Applications/XAMPP/xamppfiles/htdocs/Project-hshl-2024-main/vendor/mongodb/mongodb/src/Client.php on line 117

For all its worth I’m using an intel MacBook and all currently latest Versions of Software, application.

Thanks in advance
