Yes of course it's in dispute. It's so dominant a dispute in intelligence research that it's hard to imagine anyone being familiar with research on IQ and not knowing that it's in dispute.
IQ tests are maybe ok at doing population-level correlations, but not at predicting the success of any given individual. Tons of things are correlated with intelligence, and IQ has the virtue that it's easy to measure. So it has uses for things like research studies.
But as an actual filter when you care about performance it's not great. Things like high school GPA are easier to measure and more predictive of college success.
