CurseForge All of the Fabric 5 v2.0.6 Server v1.18.2 Fabric loader v0.14.10
I started the server yesterday and everything was going fine but today it kept crashing. 
It happens after someone joins and get timed out or disconnected, then the server shows the person is still in the server and crashes a while after. 
I need help on how to fix this asap as I'm playing with my other friends and don't want them to wait long. Crash log mlco-link: https://mclo.gs/KGwD5l9
After reviewing the logs with my Mod-coder friend, I noticed this error:
[17:07:24] [Netty Epoll Server IO #1/ERROR]: Could not serialize net.minecraftforge.server.command.ModIdArgument@194733a9 (class net.minecraftforge.server.command.ModIdArgument) - will not be sent to client!

^Does anyone know what this means?
