I think I shouldn’t had opened an issue on both Jupyter and Python. There was a duplicate in vscode-python that you moved here: https://github.com/microsoft/vscode-jupyter/issues/3925

  • The “Log” in the top post is actually from the Jupyter output. The “python” mention is erroneous (copy pasted the bug report form, but changed the log) image

  • Yes, Jupyter is running fine.
