After building any apk, it fails to install, why?

Question

android studio

Installed the latest version of Android Studio as of today. At first I wanted to build my application, but then, for the sake of persuasiveness, I created an empty project and decided to test it. In general, the result is deplorable everywhere, and I cannot apply Google's answers to myself.

Tried manually through adb start-server, but then the list of virtual devices is empty when you click on Run and such an error.

22:37	Error during Sync: Unable to open sync connection!

How to fix?
