I created a mod pack, when trying to create a world/enter an existing one I get the screen: errors currently selected datapacks prevented the world from loading you can either try to load it with the vanilla datapack "safe mode", or go back to the title screen and fix it manually

I was looking at the compatibility of the mods and everything is correct, but I don't know why this happens, if in other versions I have made my own pack of mods and this does not happen, and mentioning that the "safe mode" button does not work when pressed, it freezes for a second and nothing happens
