Answer 1

Supported Products :
Microsoft.VisualStudio.Community
Version : [17.5.33627,17.10)

This means , this extension supports VisualStudio version 17.5.33627 <= version < 17.10.
Therefore, if you update Visual Studio 2022 to 17.10 or later, it will refuse to install the extension.

It is possible to force installation by downloaded VSIX from the marketplace, open it as a ZIP file, and modify the extension.vsixmanifest in it.

Answer 2

If you are using VS2022 17.10 or above it already includes GitHub Copilot and there is no reason to install an extension. This is stated in the extension's Description which says "GitHub Copilot Completions is an AI pair programmer that helps you write code faster and with less work. For Visual Studio 17.10 or higher, GitHub Copilot (Chat and Completions) is built-in, it need not be installed as an extension."
