I cannot download that DirectX-Graphics-Samples

Failed normal Download ZIP

When I click the [<> Code] button and "Download ZIP", then I got a corrupted file (Windows cannot open the folder).
Note that I repeated the same process so many times since many months ago because DirectX 12 is very important, but still failed. I tried 7-Zip to force extract but there are a lot of missing files then.

Failed when using git clone

The latest percentage I remember stuck on 27% (500 MB+), because it's too slow, not normal, but when I came back then it's suddenly 100% (failed). The reason I download from Linux is the normal Download ZIP from Windows didn't work, and I was hoping that it will work on Linux but it doesn't work.

Questions

Is it possible to fix that problem? Should the administrator reupload the DirectX Samples? Or should I wait for the release of DirectX 13 because it's impossible to learn DirectX 12?

I asked the question in this link but a community expert said that the issue is more related to GitHub and my machine: https://learn.microsoft.com/en-us/answers/questions/1112283/how-to-use-the-d3d12-raytracing-fallback-layer.html

No repository file, test, or code entry point is identified. Start by reviewing the reported GitHub Download ZIP and git clone failures and determine whether the problem reproduces independently of the reporter's machine. Done means establishing whether the repository or GitHub hosting is responsible, rather than changing the DirectX samples without evidence.
