Typing too much chat in a single-player game (frequently) will result in kicking out of the game, but it will return to the server (multiplayer) list after kicking

Hello, Minecraft Java Edition developer, I am a Chinese player, today when playing single-player (version: 1.19.2) with a script frequently into the chat, about 10 seconds (about 25 messages), I was called up from the game, it said that my connection was lost, the following button is: return to server list.
I do have a server in my server list, as I understand it, this server has a chat detection plugin installed, 10 minutes ago I played this server and everything works, I also tried to check my game files, there is no problem, I think that single player and multiplayer servers may collude for a while, hope to solve it, thank you!

P.S. I tested the performance of the computer with a script, but I didn't expect to trigger this bug, I didn't mean to cheat
