Yup, same problem here on PC. Tried just about everything (reloading before the bug multiple times, meditating, leaving the area and coming back later, pulling out my sword/using signs to scare the nearby NPCs, etc). Even after doing the High Stakes tournament which moves around all the NPCs in Passiflora she remains non-interactable.
Really irritating bug that seems like it should be a pretty quick fix, I've seen about 20 of these threads either here or on reddit and not a single official response.
