In my case, I upgraded some nuget packages to net core 2.2, but I did not have the net core 2.2 sdk installed, so I went to net core website to download the latest sdk or runtime package, and then I did a net stop was /y and then a net start w3svc in the CMD as administrator. Problem solved for me.
