Come back to the thread if the pattern repeats, because repeat stuck sheds are a husbandry signal rather than bad luck. Usually humidity, sometimes a warm side that has drifted cool.

The other thing to watch for is her still refusing food well after the shed is finished, especially alongside weight coming off or a tail that is thinning. That is not shed behaviour any more. A humid hide, a proper gradient and a weekly weight in grams prevents most of this, and the weight is what tells you which problem you have.

Feed her today. Most geckos are hungry again within a day or two of finishing, and the pale phase you watched is exactly why she went off food in the first place. Shedding costs energy and they are not interested until it is done.

The missing skin is the easy half. She ate it. Almost all of them do, and the usual explanations are recovering the nutrients and not leaving a trail behind. It is not a meal, so it does not change your answer, but it is not a mystery either.
