Nashville more than likely wouldn't have competed in the Open Cup even without the World Cup this coming year, if SKC is any indication. But, the Dynamo did compete in 2024 after winning in 2023, so who knows.
I think it's a general rule of thumb that Open Cup winners won't defend their title because most of the time a team good enough to win the OC is going to make the playoffs, and thus probably get sent to Leagues Cup.
