Getting kicked out of World another Switch user is hosting

Both my brother and I play on Minecraft on the Switch, we started a new world back in 1.18.12.  Last night when we started playing after being made to take the 1.18.30 update, his game would freeze when saving, and I would be kicked out of his world at the same time.  The saving seems to happen more frequently in 1.18.30 and thus I am getting kicked out of the game constantly.  The message MC tells me is I was disconnected from the server.  As it stands Minecraft on the Switch is useless for my brother and I to play together.
