This could also be an issue with mac OS Catalina. Other apps are also doing this with ZIP files and if you try reverting the file association to the default Archive Utility app, instead of the OS ZIP icon you'll get the same white page with the Archive Utility icon in the middle.
This isn't exclusive to ZIP icons either. I've seen it with GZ archive aswell.
macOS 10.15.1 (19B88) still has the issue as expected, since it was not fixed in the betas.
@Euiyeon I did lots of tests, with multiple icons and empty app projects, always with the same results. Then @Deathlike shared the screenshot of the same issue in Archive Utility. Also contacted with Apple Developer support and they told me to fill the bug report.
Again, all users facing this issue should report it to Apple using the Feedback Assistant app.
