Thank you for filling this issue and sorry you're running into this
Looks like the ipykernel dependencies (namely pyzmq or the like area not installed correctly) , it's not an issue with vscode

please try reinstalling them
Optionally pleasercreate a virtual environment, (or use conda) installing packages into global python envs is generally not recommended and prone to run into issues such as this.

I am using the official vs code python dev containers
mcr.microsoft.com/devcontainers/python:1-3.12-bullseye

I believe this is managed by VS Code itself? What do you recommend reinstalling here? I thought it comes with the needful dependencies. @DonJayamanne

fwiw: I did a reinstall of whole package for now. Seems to be working inside the dev container

pip uninstall ipykernel
pip install ipykernel
