This is the Photoshop Elements forum, not Photoshop CC.

This problem usually happens with photos shared with phone apps. The solution is usually to open the file in a simple image editor - even the Microsoft Photos app and save the file again, even overwriting the original image. (But you may want to copy the image first until you are sure that this solution works for your images.)
