Where can I download your old builds of the program?

I understand that you only engage in Microsoft Store, but can download old builds?

You would have to build it from the source code yourself, but if you want that style it's still available in Settings -> Look & Feel -> Design theme -> Windows 10 -> Restart App

I can't install the app, itself because I have Win 10 1909, and there Win 10/11 20h2, can at least invest in archive.org, or on the actual github.

Microsoft Store doesn't allow users to download old versions of an App. You need to clone the repo, checkout a git commit from old version you want, and build it yourself.
