Being blind to the existence of a problem is altogether different from seeing a solution. But when is “I don’t see the problem” ever said as a confession of ignorance?
There’s also the common case of sensing the presence of a problem, and trying to answer it before the question is really understood, like a child trying to feel out the answer of a barely grasped math problem.
Compared to recognizing a problem clearly defining it, inventing solutions is trivial — which is precisely why everyone wants to bypass the problem and skip straight to ideation. And, of course, denial is easier still.
