Yes! I work in quantum information theory and this recently happened in a subfield called resource theories. The generalised quantum Stein's lemma [1][2] is (or was) a very powerful result that was used for over 10 years to prove things in this subfield. However last year it was noticed that there was an error in the proof of this lemma, and a whole bunch of results based on it weren't valid [3][4]. One of the authors of the paper where they wrote about the error gave a talk at the conference QIP 2023 this year, and there is a video of that talk available here [5]. Bartosz is a good speaker…
