Minecraft version - Minecraft 1.20.1
Mod loader - Forge 47.2.20
Mod version - 1.8.5
I am using the latest version available - Yes

Describe the bug
I can launch minecraft, create a new singleplayer world, but as soon as it loads to 100%, the game crashes with the error:

The game crashed whilst exception in server tick loop
Error: java.lang.NullPointerException: Cannot invoke "net.minecraft.resources.ResourceLocation.equals(Object)" because "attributeId" is null

Additional context
Running sinytra connector, attached Modlist.
Tried removing these mods to see if they affected anything:

• Apotheosis (and all related addons)
• Shield overhaul
• Cataclysmic Combat (removed entirely)

Responsible conflict was the Unionlib mod :/
