Entity is "null"

[og-sketch12]

Describe the bug
It kicks everyone and makes the server not joinable as soon as you spawn an entity let's say: zombie.

Software brand
Pufferfish 1.19.4

Plugins
ViaVersion, ProtocolLib, Matrix, Libs Disguises, MythicMobs, and alot more.

How To Reproduce
Steps to reproduce the behavior:
Example:

1. I'm on 1.20.1
2. Spawn zombie with command or egg
3. And boom, you're kicked and can't join until the zombie dies

It's fine with the old version: 2.2.1, entity is "null"

we would need an error for anything to look into here, if this is even a packetevents issue
also, which packetevents version are you using here?

Probably related to: #803 and #850

I'm using the latest 2.3.0 version, though 2.2.1 works fine (there isnt this error) but some plugins that depend on packetevents ain't working or loading up which loads up with 2.3.0

With the latest (as I saw in other related issues) 2.3.1-Shapshot, It says:

With the 2.2.1 version (which works but.. spamming my console with an error:

Hello,

That's another issue, which has been solved in a previous commit. You can use the 2.4.0-SNAPSHOT for now which should solve your ViaVersion issue: https://ci.codemc.io/job/retrooper/job/packetevents/

Kind regards,
