Peacock

I've been playing it for over a month now but suddenly since yesterday anytime I open it or invite my friend it crashes. It gives me this error: The game crashed whilst exception in server tick loop Error: java.lang.NullPointerException: Cannot invoke "net.minecraft.resources.ResourceLocation.equals(Object)" because "this.lootTableId" is null And here is the complete crash report: https://paste.ee/p/w5td3 I've tried rolling back some mod updates to see if it helps but still crashes :( Any help would be appreciated on how to fix or what's causing it, thank you
