It seems a perfectly reasonable possibility that Navier-Stokes is just the most easily solvable of the remaining problems, and that their new model is capable of solving it while not being capable of solving the others.

There's many cases of researchers racing to solve various problems after hearing that others are working on them. I don't think anyone's suggesting that it was a coincidence at all. In fact, OpenAI freely admits that they started working on the problem after hearing rumours that others were close to solving it. To me, that's not evidence of "cheating" in any way.
