The following seems to have gotten rid of the error for me, occurred on a fresh install:

pip install ipython pip install ipykernel

If you already have a kernel installed, upgrading it may work too. Try:

pip install --upgrade ipython pip install --upgrade ipykernel

I have the same problem on MacOS. It seems to work after pip install --upgrade --force-reinstall, ipython kernel install and reinstallation of the VSC python extension.
