The game crashed whilst exception in server tick loop

[Jamope_]

Hello everyone,

So I installed a modpack with CurseForge for the 1.20.1, it's called New Game Modpack, and the world created well and all but when I open LAN to use Hamachi for my friend to join, the game crashes with this error:

I read in some forums that it may be caused by Optifine, but this modpack hasn't it... I would appreciate some help!

 

Thanks!
