So if you come earlier, you can interect with the chair or not ?
If yes, Judy still not there after the "waiting" ?
If no, annoying bug

In your place, I would save the game (on a new slot) just before arriving on the balcony, like before the ladder and will try few times (Waiting to arrive on time, Skip time to arrive too soon, skip time to arrive too late). Or simply doing a GIG/Quest before.
Anyway, you can take a screenshot (it's better) and report it to CDPR Support.
