Updating enchantments to 1.21.5

I'm porting a datapack from 1.21.1 to 1.21.5, and for some reasons enchantments are just not being loaded, just like they weren't in the /enchantment/ folder, they just go undetected. Why? I've been looking at both the 1.21.4 and 1.21.5 changelog but I can't find anything about enchantments directory changed or whatever.
