To slow respond and error on multiplayer

Since update 1.20.30 the game takes a while to respond to certain actions, such as opening doors, opening chests, in a fight and you die in an instant because it lags, also in multiplayer mode, it tells me that an error occurred in multiplayer mode and it stops. My computer has a Core i7 12700kf along with an NVIDIA RTX 3070 TI video card and I had no problem with any update until now.
