title: VS Code kernel is empty
body: <p>I got a issue that can't run python in VS code, I have already install the python 3.8.5, and VS code python extension, if I switch to the 3.8.5 it shows this kernel is not started, and if I run the codes it will ask me to install the Data Science component and ipykernel, after I install the ipykernel it will switch to empty kernel automatically. Please refer to the screenshot:</p>
  <p>Thanks.</p>
