The property obj does not exist on WeakReference. Did you maybe forget to declare it?

        }

        /**
         * Create a new weak reference
         *
         * @param T $obj
         *
         * @return WeakReference
         */
        public static function create($obj): WeakReference
        {
            return new self($obj);

The call to WeakReference::__construct() has too many arguments starting with $obj.

        }
    }
