Welcome to the forums
There really are only a few things that can cause the focusing ring to jam on a simple prime lens like this... Either (a) the lubricants in the focusing helicoid have dried out, (b) dirt and/or debris has become lodged in the focusing helicoid, or (c) something is stopping the optical block from moving back and/or forward (perhaps something broken off internally). Either way, the solution is to dismantle, clean and re-lubricate the lens.
