Creating a mod addon/expansion for Minecraft Forge 1.20.1 MCreator 2024.1

I have been trying to create an expansion for the mod Born In Chaos with permission, and I have 2 weapons done. I need to be able to use an item from that mod and I got as far as putting the mod's .jar into my run folder in Mcreator, as well as putting both the Additional Required and Additional Dependencies mod ID as born_in_chaos_v1, but it keeps crashing my game. Does anybody have a fix so I can use Born In Chaos in my client run along with my own addon?
