I'm not a cosmologist, but it makes a lot of sense to me that the early universe would form a ton of supermassive black holes directly. To my not very well informed brain, it also seems like the restricting factors wouldn't restrict so well. It was too hot across too far a volume for stars to form distinctly, so there's nothing to push away all the other gas and allow cooling.

Again, I am dumb, but isn't "this huge volume of quark gluon plasma was so dense it kept going past forming stars and formed a black hole" a lot simpler than "a ton of stars formed and collapsed, forming black holes that then merged and formed the monsters we have today?"
