Hi Manuel, I am John J.D., a fellow Microsoft user like you.
Thank you for sharing as much information as possible. You appear to be using the latest version of Windows 10, which is good.
The minimum requirement is Windows 10 version 19042.0 or higher, and it should be x64 or Arm64 architecture. If you have all of these requirements available, perhaps you can try this link and click "Download": https://www.microsoft.com/store/productId/9PM86...
Also, you can try official link of Microsoft PC Manager and click "Download": https://pcmanager.microsoft.com/
Let me know how it goes.
John J.D.
