Why is Russia facing a Strait of Hormuz-like shipping crisis?

Russia is facing a Strait of Hormuz-like situation, with Ukraine targeting 116 vessels in Sea of Azov over the past nine days. The attacks have reportedly forced Russia to suspend maritime traffic in Sea of Azov and seek alternative shipping routes. Russia exports large volumes of wheat, sunflower oil, petroleum products, steel, and other industrial cargo through the Azov Sea.
