I will not be able to do it because I am not only the host and whoever gives the host is not available
What do I do now

logs? screenshots? anything?

and whatever happens

mod list? game version?

version is 1.16.5

the mods are all working only when I come to a multiplayer world using hamachi not because the mods all work together

well but mod list? like what mods you have?

and latest.log pls (it is always generated, and it doesn't matter, has game crashed or not, it still has info we might need)

latest.log

seems like your second screenshot hasn't uploaded when you sent a comment

my friend can craft the items but I can't craft some items

try clean install, with Create only, just in case

how could you explain it better

delete every mod except Create

done

does it work correctly now?

but it cannot corrupt my world?

I'd suggest making a backup of the world.

...or generating separate world for testing and not entering any of your existing worlds

I will create a new world

ok

someone else had this error just like mine?

I would recommend creating a local server just with Create.
