The same problem occurs for me as well.

Please could you enable logging as follows:

  • Open settings & go into Jupyter->Logging
  • Change the value to trace
  • Reload VS Code,
  • Attempt to repro the issue & then copy the output from the Jupyter output panel (use the command Jupyter: Show Output to get to the logs).

DonJayamanne avatar Dec 10 '25 00:12 DonJayamanne

@DonJayamanne I already attached the logs in the issue, do you need any other logs?

phi-friday avatar Dec 10 '25 09:12 phi-friday

@DonJayamanne I just ran it and checked the logs. It happened after restarting about four or five times.

I have the same issue, I think it started 1-2 months ago.

I have tried disabling all extensions, I currently only have Jupyter and Python extensions enabled (even Pylance is disabled), issue still persist.

It also seems to be ignoring timeout/retries parameters, as it has been stuck restarting for the past 10 minutes.

I think it might related to ipykernel==7.1.0 version, I downgrade to 6.30.1 and it works.
