You get paid. You prepped the room, you didn't book anyone else. The problem was on her end.
however, don't spend the money yet! She may call Airbnb and plead "extenuating circumstances". If they agree they will refund her ( just YOUR money, not their percent) and it will come out of your next booking payment.
If she writes you and you feel soft, you can refund her partial money in the resolution department but you are training her that host cancellation rules don't mean anything.
You could also keep the money and make her a special offer if she returns in future.
but you are not obliged to do anything, you have earned your money!
