CANNOT PLAY, disconnect immediately when kill any monster.

hi，GGG

Last night, I dropped a red mushroom in the sunken city. I had just gathered three types of mushrooms, so I picked up the red mushroom and went to the big pot. However, when I opened the inventory, I found that the red mushroom had disappeared. I was very sure that I had just picked up the red mushroom. It's strange, but I didn't pay much attention to it, so there was a crash in the next 10 minutes, and then I restarted the computer as usual. Then something strange happened, as soon as I hit the monster, it would immediately freeze for 4-5 seconds and then disconnect back to the login screen, unable to play the game normally. Creating a new character will also cause all parts that interact with the server to freeze and disconnect, returning to the login screen. How should I solve it?

plz help me!
