Mario Kart 8 Deluxe - 100 friends glitch causes issues with private rooms

Do you have more than 100 friends on Switch? If so, you're going to have an issue when it comes to playing in private rooms with friends in Mario Kart 8 Deluxe. Instead of being able to make a room, you'll get a message saying that you don't have any friends at all, and you should add some. Right now, the only fix is to remove some people from your list.
