And even it was second generation, being a remnant of a 60 solar mass supernova.

There's another article:

SM0313: Oldest Known Star Discovered | Astronomy | Sci-News.com

"The astronomers also measured the abundance of carbon in SM0313, and
found that this element was in much higher supply – more than 1,000
times greater than iron."

So it sounds like the first gen star was strong enough to spew out its
carbon in its outer layers, but not not strong enough to push out its
iron in its inner-most layers. It's likely the whole iron core was
swallowed by the resultant blackhole. And that any iron in that got into
the second generation star was as a result of endothermic processes at
the explosion.
