[Crash Report] Prevent access to the server.

[McReiz]

Minecraft and Mod version 🐞 Minecraft: 1.20.1, Quilt 0.9.2, Mod Version: 5.6.0

Description of the crash 💥 After spawning an NPC, configuring the NPC, and restarting the server, it no longer allows access to the server.

Steps to reproduce the crash ⚙️

1. Configure the NPC to give an 'Advancement' using the execute command.
2. Restart the server and wait for it to start.
3. Enter the server and cannot access it; the following error appears: io.netty.handler.codec.DecoderException: Unknown serializer type 83 in screen

Expected behavior before the crash ✔️ This happened several times, when I delete the mod "Easy NPC", I can enter again

Thanks for the report. Unfortunately, the log doesn't point to a specific part of the code, so it's unclear exactly what is happening here.

However, the log does show that all necessary data serializers are being registered, such as:

This suggests the issue could be related to an incompatibility with other mods. I’ll try to reproduce the issue on Quilt. However, if the server is running in offline mode, there could be other factors causing the issue that I might not be able to replicate on my side.
