3Does this answer your question? Given Newton's third law, why are things capable of moving? – DanDan0101 Nov 28 '21 at 04:50

When thinking about Newton's third law, you mustn't think that the action and re-action nullify each other, because they are acting upon different bodies. You have to consider how each force independently affects the body it is acting upon. In the case of the block on the spring, there is only one force acting on the block, which is the restoring force, so the block is going to move as there is no other force holding it back.
