Every time when we want to go in the end your game crashes.

It happens with out reason.

The game crashed whilst rendering entity in world
Error: java.lang.NoSuchMethodError: 'net.minecraft.client.model.HumanoidModel net.minecraftforge.client.ForgeHooksClient.getArmorModel(net.minecraft.world.entity.LivingEntity, net.minecraft.world.item.ItemStack, net.minecraft.world.entity.EquipmentSlot, net.minecraft.client.model.HumanoidModel)'
Exit Code: -1

and this is the crash report we get when the game crashes.

Have you checked with the server in which you host with? They might provide some insight faster than this thread will.
