Have you checked if is the lens issue or the body? Do send to nearest shop and ask them to inspect in front of you and see which causing the problem.

But from my experience, it's usually the lens. Just send for warranty if there's still any, or buy another one.

Oh the physical won't have much damage but internal might be already tali putus or something. I once had my Sigma 10-20mm dropped while my friend tried to lock into the body. The lens is totally fine but could not be used. When I sent to check, organ inside kaput sudah, need to find replacement.
