The survival kicked me and my boyfriend out while we were in the end and now it won't let us join back.

I posted a bug report but I domt know what else to do I just want to hop back on and play
 
What error is shown when you try to join back?
What version are you using?
What platform are you playing from?
Do other gamemodes work?
Any Mods/Client Side Modifications?

Internal Exception:
io.netty.handler.codec.EncoderException: Failed to encode packet 'clientbound/minecraft:set_entity_data'

Were on java 1.21.10

Everything else let's me join but survival, when I try to join it always sends me back to lobby with that same error message



I recently installed the simple voice chat mod but I deleted it bc of that error message
 
So using 1.21.10 is good since Survival is on the version which Survival is on too.
Using Simple Voice Chat Mod should not cause any issues.
Since this also only happens on Survival I have concluded a probable cause of the issue:

The Error mentions a falsely encoded packet from "set_entity_data". I could go into more technicalities if you wish but I won't for simplicity.
Almost always the issue is a broken mob in the world. This includes but is not limited to custom NBT from commands, corrupted mobs from older versions or missing attributes. To be exact, there is a broken mod somewhere in the end which got loaded once you entered/got near its chunks. You will need to ask a Staff Member to teleport you to spawn.
 
Okay then it is definitely a server side issue. The server is sending invalid entity data.
As said best thing to do is ask Staff to teleport you to spawn
ok but for me it sends me to the hub immediately but for my bf its keeps reconnecting him to the survival, see his name is spicywings
