final class SessionLibraryHelper extends AbstractLibraryHelper
{
    private static ?Session $object = null;

    public static function library(): Session
    {
        if (!self::$object instanceof Session) {
            $settings = ConfigLibraryHelper::getSettings('Session');
            self::$object = new Session($settings);
        }
        return self::$object;

The expression return self::object could return the type null which is incompatible with the type-hinted return WebServCo\Framework\Libraries\Session. Consider adding an additional type-check to rule them out.
