My physical copy of Monster Hunter Stories 2 requires a software update for some reason

Yes, I am aware of the news about the misprint, and that apparently the game doesn't require a download. It's the main reason why I double dipped and bought the physical copy despite already having bought the game from the Eshop. However, I am unable to open the game even on airplane mode. When opening the game, it says "A software update is required. Update data will be downloaded now" with only Cancel and Download being the two options.

I tried all sorts of things, such as deleting my digital copy of MHS2, turning on airplane mode, and even deleting my save data. However, none of these things helped me.

What should I do?
