My brother plays Minecraft on his Nintendo Switch and joins my world on Xbox. About thirty minutes after joining, every GUI takes forever to load or fails to load completely. For example, opening the inventory, a chest, or using a crafting table (anything that brings up a GUI) hides the inventory bar and a loading bar appears across the screen. He is unable to move his character or interact with anything until the GUI finally loads or his game crashes. The connection, however, still functions, as he can still see my character waking around and interacting with blocks and objects.
