Struggling with a Packaging Pop-up

I’m trying to make an escape-room type game with the displayed version of Unreal. Everything has been made and tested, so it’s ready to be packaged. Unfortunately, every time I try to package the game, an error and pop-up message appears and I have no idea how to fix the problem. I am packaging for Windows 32-bit under the Development setting. The game doesn’t use C++ code, only blueprints, matinees, and widgets. I have attached 2 pictures that illustrate the problem I am having. If you know of a solution, please let me know as soon as you can, and thanks.
