Can't watch videos right now, but the wikipedia article says the problem has been solved around y2k by recalculating the age of the universe, and says nothing about JWST making this problem worse.
Some astronomers are looking at JWST data and claiming they are seeing galaxies with red shifts in the range of 11-20, which if accurate, correspond to ages older than we'd expect to see galaxies of such size formed. Other astronomers disagree, and believe that the results aren't so clear. This the "hubble tension" or "crisis in cosmology" maybe still live on.
It is exciting, either we get more data to confirm our current understanding or we need to discover be physics and form new theories that align with the data. Either way is great, imo.
