There may be another issue at play given she's not eating, but otherwise a ball python typically doesn't move much on principle compared to other snakes. They are both nocturnal and ambush hunters (meaning they stay in one place for long periods of time waiting for prey to pass by), which means they not only don't have much reason to move, but the times they do move are likely when we're sleeping.
My own BP is very much the same as yours, explored a lot when he first arrived and then hunkered down to one hide and almost never leaves it. He has other hides, he has enrichment in fake foliage and climbing branches, but he's content to stay in the same place 90% of the time. Yet despite that he's perfectly healthy and eating heartily.
Again there may be other things to look into considering your girl isn't eating, but on a base level a stationary ball python is pretty normal in most cases.
