same here, bought the rope and whatever interaction there must be simply doesn't trigger. this is fucking retarded.
just tried reloading and buying the rope in advance, well, the hook you'll also need is not available until you get to the temple. So unless there's some 500IQ solution to this, the game is plain bugged. Did anyone test this before release?

go to %game_folder%/game/maps and open the file desertMapSecondTemple.rpy. In there, on line 495 there will be a line:
'if QueenPoint9.condition == 1:'
Delete it and fix the indents so the next condition is on the same level, like this:
