I'm not an expert but from what I understand, scientists observed the very distant galaxies which shouldn't be visible according to most popular model of the universe evolution. And if these observations will be confirmed then we might get more accurate model which totally differs of the most popular one the scientists agrees upon.
Far distant young galaxies should be seen as "red", but these aren't and that's the issue here - JWST captured these very bright. It's possible that the universe evolves in a different way and Hubble's law doesn't applies
