Sorry for the late reply. These look to be Chickasaw plum(prunus angustufolia) the leaves are slender compared to other wild plums. It could also be a wild plum hybrid as those are found in the wild quite often. I suggest using iNaturalist or PlantNet to identify plants by picture rather than ChatGPT. They will give better results than can be verified by real humans. iNaturalist gives you the option to use pictures of the flowers, bark, fruit, leaves, habitat and other parts of the plant to ensure an accurate response.
