Additional Information

I am unsure if it is 'Datapack Anvil' that is causing it or if 'Elemental Craft' is to blame.
'Elemental Craft' is dependant on 'Datapack Anvil'

'Elemental Craft' is listed as alpha releases for 1.18.1 still, so it might be something that gets fixed on their end ones a more stable release is out.

I have no idea if it also happens in multiplayer, but my guess would be that the same error is thrown when joining any server.

Sorry Just noticed that #450, already exist for this issue - will close this as it is a dupelicate.
Perhaps i did add more info thought...
