Rechercherichtung
Start by reproducing the failure in the VS Code Jupyter environment described by the stack trace, using the ipympl widget. Inspect the WidgetManager.loadClass and handle_comm_open stack entries in ipywidgets.js and ipywidgetsKernel.js, then compare the installed Jupyter, renderer, and widget versions. Done means identifying the trigger and confirming that the intermittent JavaScript error no longer occurs.
