Crash when connecting to player-hosted or realm world with many add-ons.

Some of my friends have issues connecting to player hosted servers or even the realm with mods active on. We all have xbox series x, and fast internet so downloading shouldnt be a problem but anything over 30 mbs and they crash, on realms or hosted. we have to individually update each mod and sometimes that doesnt even work. its made some of my friends frustrated with playing.
