This is a very common error. You may be in a rush, or doing too much multi-tasking, then open VS Code expecting to see the IRIS icon signifying your favorite programming extension is ready and waiting. Then to your surprise, it's missing! The likely problem is that you haven't opened a folder yet in VS Code. Just do that and you should see the icon again.
Thanks, Evgeny.
I open a folder, the icon appears now.
