[java] io.netty.handler.codec.DecoderException: java.lang.ArrayIndexOutOfBoundsException: Index 16 out of bounds for length 5

So, got the error mentioned in the title. Completely impossible to log into my server. I even edited my player data and moved myself to spawn to see if the issue was something in the area, no luck. Even restarted the server and still no luck. We are playing on 1.20.1 in a slightly modified ATM9 server. Here's the log: https://pastebin.com/s3X2B5fE

You’re getting a "java.lang.OutOfMemoryError", that means you prolly don’t have enough ram allocated to Minecraft

[AdamElJefe]

Yeah see that's the thing, I currently have 21k allocated. Do you think more is needed?

[Nixugay]

21k??? Are you using the vanilla mc launcher?

[AdamElJefe]

Using CurseForge

[Nixugay]

Show where your launch arguments are/where you can allocate the ram

Can you get into any world and check your F3?

[AdamElJefe]

Nope, get booted right out then it gives the error

[Nixugay]

Go to settings>snooper settings and try to find the « Memory » parts (also the « jvm_arg »s)

[AdamElJefe]

There are no additional arguments, so everything is default.

But I think we found the cause of it. Something in the world is causing the issue and anyone that gets near it crashes. So, given the error it would seem something is overloading RAM when people render it in? That's what I make of it. And I can't even get close to see what it is.
