Has any significant problem of modern philosophy ever been "solved" in the sense that most scholars agree on one position, or is it always an ongoing argument and a multitude of opinions?

edit: thank you to everyone for your answers! Many interesting takes and references.

If you take a theory/position in philosophy X and ask "Is X true?", then that's arguably a problem in philosophy. And if X has received some amount of attention in philosophy it's a significant one. So you'd 'only' have to look for positions which are incredibly unpopular, then most scholars agree on the position that "X is false".

If you look at the often cited philpapers study, you can find a couple of positions which the editors deemed significant enough to list as an option but have less than 5% support, so presumably >95% would answer "no" to "is X true?".That would include skepticism about the external world (4.8%), idealism about the external world (4.3%), relativism about knowledge claims (2.9%), and something called sense-datum theory about perceptual experience (3.1%).
