vscode: Remote SSH Connection Crashed after openning a Jupyter Notebook on the remote server

Does this issue occur when all extensions are disabled?: No

VS Code Version: 1.83.1
OS Version: Windows 11 latest

Steps to Reproduce:

Open up a remote ssh connection to a remote server
Open a Jupyter Notebook stored on that remote server. It can be a brand new Notebook or something already existed.
VSCode crashed with “Cannot reconnect. Please reload the window.”

It could be a problem with VSCode, or the Python / Jupyter extension. This did not happen with VSCode 1.83.0 so something in the update could have messed things up.

We figured out it was caused by Pylance extension killing the remote extension host process (see details in https://github.com/microsoft/pylance-release/issues/4983). The Pylance team has fixed this issue in both Stable and Prerelease. To ensure you can get the update before VS Code remote extension host crashes again:

Open an empty Remote SSH window (Remote indicator -> Connect to Host … -> Pick the remote)
Open extensions view and find Pylance, upgrade to latest v2023.10.40

Let me know if it fixes for you.

My solution is downgrading the jupyter extention to v2023.10.1002931100 (but I dont know my last jupyter version, just downloaded the second version from vscode office website), that works for me.

I’m seeing the same problem when connecting to Remote-SSH as well as WSL. occurs in both “code” and “code-insiders” (from MS App Store). Specifically occurs for me when attempting to “Select Kernel”.
