Drop image repeating error

Hello, I was working on Your editor as usually, but today the same error occuring repeatedly. When I want to open some existing project, or if i want to drop the photo to some project, it will automaticly create some shield with the message that I can drop to add the file, but it will never come off of the screen. it`s on every my project when I open any. Today it`s doing the same from when I started with Adobe Express, so basicaly I haven`t done any work today. Please, help me with the problem. Thank You so much , I appreciate it. Klaudia
