FrameworkException Missing Extension

I have just installed codeigniter 4 and I'm receiving the following error

PHP Code:

foreach ($requiredExtensions as $extension) {
            if (! extension_loaded($extension)) {
                $missingExtensions[] = $extension;
            }
        }
 
        if ($missingExtensions !== []) {
            throw FrameworkException::forMissingExtension(implode(', ', $missingExtensions));
        }
    }
 
    /**
      * Initializes Kint
      */
    protected function initializeKint()

I have already enabled intl extension but it's still saying that it cannot find it. I have even restarted and done a full clean and install but till receiving this error
