I have an Xbox one and my world is only 95.5 MB but it loads for a few minutes and I can only stay in the world for 30 seconds before it freezes for a second then quietly kicks me back to the Xbox home screen, no notifications or anything pop up. Is anyone else having trouble opening other online games after getting kicked from Minecraft? Between me and Xbox support, we narrowed it down to solely being the Minecraft world.
The update solved my world too! Thanks Mojang and everyone in the comments for letting me know.
