There are a couple things that it might be. The first is that it may be brown rot. This will rot the fruit on the tree and cause it to shrivel up. Here is more information on that: https://www.gardeningknowhow.com/edible/fruits/peach/brown-rot-fungus.htm
The other is the flowers are not being properly pollinated. Improperly or under pollinated fruit will be aborted by the tree early on and can simply just shrivel on the tree.
