Error when loading singleplayer world 1.21.1

[LeFakeOff]

So I'm currently making a modpack for 1.21.1 neoforge and I wanted to have mekanism in it but when i try to go in a singleplayer world i get this error :
Internal Exception: io.netty.handler.codec.EncoderException: Failed to encode packet 'clientbound/minecraft:update_recipes'
I tried without the mod and the world is loading fine
Here's the log if you need it

Now it has been fixed, you can download version 1.0.2. :)

btw, the logistics transporter can cause the game to crash. Please do not use it. I am trying to fix it, but it will take some time
