Until very recently the most distant object our telescopes can see had a redshift of about 14, but very recently there are reports that the James Webb telescope has seen point-like objects that seem to have a redshift of 25! Whatever these objects are they contain little or no dust as you'd expect because dust requires elements other than hydrogen and helium which need to be made in stars, but if we really are looking at an object that has a red shift of 25 then we're looking at something that existed before stars did. If confirmed that would be a pretty profound discovery, and about the only thing that could explain them are Primordial Black Holes created during the first nanosecond after the Big Bang.

I too had thought these were generated in the earliest moments. However, The JWST has found these little red dots which increasingly fit a model as superstars. Hyperstars were proposed by Feynman and Wheeler as 10^5 to 10^6 solar mass stars, which might have a black hole within them. The interior black hole might have been generated by BAO fluctuations in the very early universe. The question is not answered about these.
