Well, I'm curious what the solution is because everything I can come up with only works with black playing imperfect. Closest I can get is rook to b4. Black only has one move to prevent an instant checkmate. Rook to a8.
It has a "forced" mate in 2. So it's not that the puzzle is solvable if black plays sub-optimally. You may try your approach on the interactive board link shared in the post. It will let you try moves without giving hints so that you can learn from your mistakes. If you're stuck then click on "Analyse" button which can help you see different variations of the puzzle. Hope that helps :)
