Everytime i try to join or make a world with this mod (Fabric, 1.18.2), minecraft tells me there's an error with a datapack i am using (Is a mod the same as a datapack or not? Because i am not using any datapacks if it's something different than a mod). Then Minecraft gives me the option to use safe mode or go back to the title screen and fix it myself. Safe mod doesn't work by the way.
I tried to find a solution but couldn't. Can anyone help me with this?

Edit: Making a server with the mod (using Aternos) also makes the server crash when starting.

Same problem here. Fabric, 1.18.2, never used Chipped before. Can't open any world at all if chipped-1.2.jar is in the mods folder.

(As I was checking that I had the right version I realised I had misread and it's not updated to 1.18.2. Sorry! Is that in the works?)

1.18.2 Fabric was just released:
