his crash didn't occur when playing single-player but crashed while playing multiplayer. When I checked the report, it claimed that the mod MrCrayfish's Furniture Mod: Refurbished and Framework was the reason of the crash.

Are you using a software called Velocity by any chance?

no i don't even know how to use that tho, do you need my modlist ?

i have same problem, when place a mail box on multiplayer server on velocity my client crash.
latest.log

I mentioned Velocity because it is known not the be able to handle custom login packets. This is not something I can fix in my mod. @mici1708

So this error only occurs if you didn't receive the configuration data from the server. This happens during the handshake, before the world data is sent to the client. It's going to be hard to pinpoint the issue because of the amount of mods you have installed which could be contributing to the issue. Do you happen to have the debug game log that corresponds with the crash? That log should tell you if you received the config data.

Where can I find it
