A few seconds after I catch her and press the x button, she starts attacking me, my character freezes in one position and that's it. I can't do anything else but move the slider with the heart. I can only watch as the ghost reappears and catches my character. And this is not the first time this has happened. What should I do?

Hello, I'm aware of this bug but due to some reasons I can't update the game for quite a while. But you can try catching her while keeping lights to her room turned off. You only have two seconds until she moves.
