does not want to work MoveTowards

Why does MoveTowards not want to work? Of course, if you turn on isKinematic then everything works, but this is not a way because the joints do not work well!

        if (other.CompareTag("Player"))

GetKeyDown only returns true in the frame that the key is pressed in. Therefore your code to move towards it only being executed for one frame each time the E key is first pressed.
That is not the only thing wrong with your code by the sounds of it. It may be worth asking a question relating to what it is you are trying to do.
