Start by reproducing the failure from the `jupyter notebook` entry point on Windows 11 with Python 3.12, then trace the reported `ipykernel`, Tornado, and asyncio stack. Compare the IOPub and event-loop errors while running `print("Hello")`; done means notebook code executes and prints the expected output without either exception.
