Figured it out: It was the custom icon file set up in the project settings for Windows deployment.
I read on the AnswerHub that you can save a .png and in the dialog box change .png to .ico and have it work. That’s not the case. Don’t do that lol
So now I just need to find some way of saving a .ico since Photoshop doesn’t seem to have that export option. But it packages so yay!
