If the supernova standard candle is wrong, it could solve the Hubble tension

Last time I wrote about new data that overturns the standard cosmological model. Before anyone starts dusting off their fringe cosmological models, we should note what this new study doesn't overturn. It doesn't say the Big Bang model is wrong, nor does it say that the universe isn't expanding or that Hubble's redshift-distance relation needs to be thrown out.
