和朋友一起玩的1.20.1的自制包，朋友频繁掉线报错但不闪退

和朋友一起玩的1.20.1自制整合包有用kubeJs做过配方之类的魔改，之前玩没有任何问题，但是最近两天，我的朋友们频繁掉线并提示Internal Exception: io.netty.handler.codec.EncoderException: java.util.ConcurrentModificationExceotion而我这个建主的没有任何问题，同时他们在野外探图挖矿也都不会掉线，只要回到家里过一会就会掉线

翻找了latest.log文件中可能是报错问题的部分给GPT看了一下说是ConcurrentModificationException问题，但说的解决办法都是很涉及编程的东西，咱实在是看不太懂
所以求助求助大佬能不能解决一下
