Same here on same new version. Game will freeze when autosave occurs and during autosave game will drop in performance for a bit.
I've had a similar issue with this as well, instead of playing multiplayer I was playing single player on bedrock Nintendo switch version. The autosave will result in a decrease in performance sometimes and also can sometimes freeze the game for about 10-50 seconds. They said it was fixed in 1.18.31 but its not. (my version is 1.18.31)
I have a different variation of the same glitch. My villagers have the default unemployed texture even though they have a job (I'm also on Nintendo switch version 1.19.20)
