Unable To Export Artboards To File

I make social media banners in 3 different sizes. Each one is on its own artboard. When I try to Export > Artboards to Files, I'm getting an error message: User cancelled the operation. The problem is I'm not cancelling anything. I need to export each artboard to a jpeg. I've tried this with 3 other files that are setup this way and the error occurs each time. I've closed PS and reopened, but it still occurs. My PSD source file is on my Creative Cloud folder. I tried putting the PSD on my desktop but I still get the same error.
