Multiplayer issues since 1.19

Since this last 1.19 update, I can't join a friend who's world I could join pre-1.19. My friend is on switch too, and he's also on 1.19.

 

Expected Results:

I join my friend's world and play with him

 

Observed Results:

I get stuck in the "joining world" screen, and then the message "unable to connect to world" pops up
