If it's Ellie's PoV, it was a later addition so the camera angle will break when a new sequence is loaded. To fix it you should get out of PoV and then go back again, after the sequence is loaded.
If you are switching between PoVs, that's another matter. If you try to switch between PoVs without disabling the current one first, it'll also break the camera angle of Free Cam mode. So make sure to disable the current PoV before switching to the other one.
