Removing Aether mods, causes crash on New World Creation

[CephalonAxii]

Describe the Bug

Hi, love the modpack. However, due to personal preference, I prefer Expanded Combat when it comes to the Gloves Curios and such, so when I removed all of the Aether mods and addons so Expanded Combat would run easier, it causes a Exit Code: -1 on me and crashes the game back to the Minecraft Launcher. I also tested this without Expanded Combat, and it still persists, which tells me it's not Expanded Combat's fault.

It seems to me like there is some sort of Datapack that makes the game reliant on Aether Lost Content's Platinum Dungeon, but I don't know how to find said datapack and remove it, if it can be removed.

Reproduction Steps

1. Remove all Aether mods, as well as their required dependancy mods, and addon mods.
2. Load the game, it will successfully get you to the Modpacks main menu, then navigate to the Create New World screen.
3. Create the new world, and it will then crash resulting in the Exit -1, Error: java.lang.IllegalStateException: Trying to access unbound value 'ResourceKey[minecraft:worldgen/structure / lost_aether_content:platinum_dungeon]' from registry net.minecraft.core.MappedRegistry$1@42063d53 ...
