Unfortunately I think you've misunderstood the logic behind unique rectangles. You can't use unique rectangles to prove a puzzle has a unique solution, as the technique itself relies on the puzzle already being unique to allow the rule to be applied.
I'm not great at explaining these things but there's definitely some good online resources that will explain it better than I would.

This puzzle does require the "Unique Rectangles" logic once near the end. There is one solution if you use that logic to make an elimination.
