How we know that Einstein's General Relativity can't be quite right

In the How we know that Einstein's General Relativity can't be quite right video, Sabine Hossenfelder explains how General relativity cannot be quite right. One claim in the video is that (general) relativity is wrong because relativity conflicts with quantum mechanics (QM) and QM is right. That is a bold claim for a falsifiable theory. A two-split thought experiment is provided to show this. This experiment – and to my knowledge no experiments so far – does not combine relativity and QM in such a way that we can rule out one of them. I do agree that theories with singularities, like relativity, generally suggest problems. Both theories, have shown to be reliable so far and naturally: both cannot be proven correct. I think that therefore, using one theory contradicting another cannot be used as proof that the other must be wrong.
