hi i have bit of problem with ATM-8 Modpack, modpack is crashing every time i start my world saving and this crash code is showing up : The game crashed whilst unexpected error
Error: java.lang.NullPointerException: Cannot invoke "net.minecraft.client.multiplayer.ClientPacketListener.m_6198_()" because the return value of "net.minecraft.client.Minecraft.m_91403_()" is null

i have increased my ram memory and even try the repair tool in curse forge and nothing helps and it has way to much mods for me to look at every one
