Please fix the bag in the new update

I am very disappointed with the latest update of Minecraft. I downloaded the game again after 4–5 months because I really enjoy playing it, especially with my friends. But now, whenever I try to join any server, the game crashes automatically. Single player works fine, but multiplayer is completely broken for me. Because of this issue, I cannot play on any servers, and all the fun I used to have with my friends is gone. This is very frustrating. Please fix this problem as soon as possible. Many players like me just want to enjoy multiplayer again without crashes. I hope this issue will be resolved in the next update. Thank you.
