Hello Mojang team! This is the first time I've had a bug like this. As such I'll list every detail I can to make sure you have enough to work with to resolve the issue.

Basically what happens is that I will open up my inventory and see that my recipe book is open, which it usually isn't, so it opened up on it's own. I'll then go over to a crafting table and try to craft something - not using the recipe book still - and it will crash.

It doesn't matter if I use the recipe book or not, as I have tried many times switching between the two.

I'm also playing on multiplayer on a 1.16.2 server with a texture pack. I have also updated the jVM arguments by 1 so it looks like the following: -Xmx3G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M
