can't download file

My original post didn't contain the necessary details, and I don't see an option to delete it, so I'm reposting with the required info.  I've also included a better example image.

Lately, when I export my YouTube thumbnails, there is a white border around the image, almost like a thin vignette. I've used this application for months and have only seen this in the past month.

Version of the app: web app
Platform and OS version: Edge browser on Windows 11 
Basic steps to reproduce the problem: export image, png
Expected result and actual result: whatever I see in the editor, without a white vignette around it.
