The James Webb Space Telescope is discovering increasing numbers of quiescent galaxies 1–2 billion years after the Big Bang, whose redshift, high mass and old stellar ages indicate that their formation and quenching were surprisingly rapid. (...)

Cosmologist will always be "surprised" as long as their model is adverse to reality.

from your ref. :

The galaxy, called GS-10578 but nicknamed ‘Pablo’s Galaxy’ after the astronomer who first observed it in detail, is massive for such an early period in the universe: about 200 billion times the mass of our Sun, and most of its stars formed between 12.5 and 11.5 billion years ago.

Every discovery i read about says current models (of the "early" universe) are wrong. For instance :
