Her voice has always been squeaky, or nasally. That's the "YG technique" that some would like, some might not like.
I also feel that some part of it is off. I think the song lacks a memorable part/choreo, unlike Jennie's solo. But probably that's not the focus for Rosé since she is going for the more toned down and mellow route
Yes I know what she sounds like. I usually love her voice but here it was extra squeaky, just a bit is fine but here she crossed the line where it turned into "annoying" squeakiness.
