Incorrect behavior when running .py files in the latest version

[kuri54]

I updated VSCode since my research activities have come to an end. At that time, I also updated the extensions, but now I can't do what I used to be able to do.

Expected behaviour

extension versions
Pyhon: 2021.8.1105858891
Jupyter: 2021.8.1054968649

1. Open the .py file
2. Create a code indent with # %% and execute with shift + Enter
3. The Interactive window appears and the code is executed
4. Close the Interactive window
5. Same behavior as 2.
6. The code will be executed again.

Actual behavior

Extension versions
Pyhon: 2021.8.1159798656
Jupyter: 2021.8.1236758218

• The code is not executed again.
• The preview window appears instead of the Interactive window.
• The message Direct kernel connection broken is displayed.

The icon displayed in the Interactive window seems to have been changed.

Steps to Reproduce

1. Make sure your extensions (Python, Jupyter) are up to date.
2. Start Docker from a dockerfile with a port output to JupyterNotebook.
3. Connect from VSCode's remote feature.
4. Open the .py file and run the code.
   (Do you need to provide a dockerfile?)

I don't know which extension has the problem this time, Python or Jupyter. (Please forgive me for posting on this issue without knowing.)
I tried using an older environment for either version, but that didn't solve the problem.
I don't think the Docker connection is the problem, what do you think?

This sounds like a timing issue with creation of the kernel in the new interactive window.

Can you include your entire 'jupyter' output log? It shows up here:

I'm going to enter a separate issue for the image next to the code. That's basically the execution count missing when code is collapsed.

Thanks for replying!

Yes, it does. This sounds like a timing issue with creation of the kernel in the new interactive window.

I tried to respond to this reply, but for some reason I can't update to the latest version. I was able to do it yesterday, is there something wrong with it?

However, the log shown is as described above. I don't recall seeing any other error messages at the top of that log other than this one.I am sorry that I cannot reproduce this.

Thanks for setting up a new issue.

Closing as not reproducible anymore.
