You might want to check if Fiddler Classic is running with the necessary permissions. Ensure that it has the right firewall permissions and that it's not being blocked by any security software.

It seems Windows Store does not work correctly when proxy is used. Looks like it does not even send required CONNECT requests to the proxy, and that's why you do not see any traffic in Fiddler Classic. I've checked and there are various issues in Microsoft forums regarding usage of Microsoft Store with proxy and the solution in most of the cases is to bypass the traffic to hosts that Windows Store is trying to connect. For example, you can check here: https://answers.microsoft.com/en-us/windows/forum/all/windows-store-on-a-domain-machine-using-a-proxy/c87af4aa-2fd3-4092-a510-1c5aa2e30564 

So, it looks like it is not possible to capture the requests of Microsoft Store via proxy.
