Crash when i load one of my two worlds

The bug:
My game crash when i try to load my survival world if i have my simulation distance over 4 chunks

To reproduce
I don't know what i did to have these crashes so I will quikly discribe my world
My base is in a desert village with 20 villagers and 2 golems and i have 3 factories wich use redstone ( redstone, pistons, hoppers, comparators, repetors, observators and powered rails)

Edit: now i can't load the world, it instantly crash every way
