Edit 1 :
It also happens on the game of other players (not only on my side).

Edit 2 :
I try without OptiFine but the same thing happens.

we should still fix the crash

Ok I finally could find where the problem came from.
Some tools had kept an old enchantment of a mod that I delete since, and when one of them was present in a chest, it was crashing the game during the search.
This enchantment was now invisible, so no choice to throw almost all my enchanted tools into the fire ^^ '

Save those poor tools from lava! :D
