In Chapter Fatal Affair:

When I use the power for her to jump out she simply tells me that the object is far away.

It's been a really long time since I ran this so I can't remember the details, but I think it had something to do with one of the gun glitch sections being done at a certain timing which messes up the game and causes this.

If the bug is what I think it is and I remember the chapters correctly, then there's a bug where if she reaches the ledge and you don't manage to grab her before she does, she just kinda softlocks and won't jump. If this doesn't work try tossing me a video file that works and I'll see if I know.
