AI Agent said the root cause is: Cursor's Jupyter extension (version 2025.3.0) is incorrectly expanding the home directory path using Unix-style ~ expansion, which is invalid on Windows. The extension is trying to create a path with ~ in it, which Windows cannot handle.

Updated to 2.0.77 and it's working! Also noticed that the Jupyter extension was updated on 2025-11-11 to version 2025.4.1.
