Local variables not displayed in Jupyter Panel during debugging with Python 3.13.0 in VS Code

Type: Bug

This issue with the Jupyter extension in Visual Studio Code occurs when debugging a Python script that reaches a function. In this case, the local variables of the function are correctly displayed in the "Run and Debug" sidebar, but they do not appear in the Jupyter panel, which only shows the message "loading variables." This bug seems to be specific to the new Python version 3.13.0 and does not affect previous versions. It could be due to changes in the handling of local variables or in the debugging interface between Python and Jupyter in Visual Studio Code, possibly requiring adjustments in the extension to ensure compatibility with this latest version.
