3 weeks ago @DonJayamanne, this issue has happened only once. I have been using VS Code and Juypter regularly for over a year now and this is the first time that the problem has appeared. I did just update VS Code with the latest available, so perhaps something changed in the latest version?

3 weeks ago Thanks for the prompt response.
We haven't made any changes in this space, its more likely related to some other issue we're looking at. Most likely a duplicate of https://github.com/microsoft/vscode-jupyter/issues/15716 Given that you cannot repro this and we have a similar issue, lets close this for now, as unfortunately theres' not much we can do at this point. Please do not misunderstand me, i'm not saying I will not fix this, but without repro steps or the like, its difficult to resolve this. Also its possible its just a dup of the issue mentioned earlier.
If however you do run into this, please do check the logs again & share the full logs (the contents in the logs before the error is crucial in this case), it would tell us whether the notebook was closed or a cell was deleted (visually the notebook may not be closed, however the notebook object may have been closed/disposed which results in such errors).

3 weeks ago @DonJayamanne, please tell me more about the logs you need.
Is it from the same Output window from which I copied the logs in this bug? If so, there were no other recent entries: the prior entries were from some hours before describing that I had started a debug session. (I know this because I used the timestamps to determine which parts of the logs to copy.)
Also, I had not closed the notebook (or any file for that matter) at the time of the issue, nor had I deleted a cell recently. The most recent cell action was likely the addition of a cell before going to edit the cell that raised the issue. The new cell was several below the cell where the error occurred.
It is understood that you need more info. Sorry the detailed logs were not enough. Let me know what you need in case it occurs again.

3 weeks ago @DonJayamanne, FWIW here are the logs for a few operations before the one that had the above error. Looking closely, there were other instances of the "notebook controller is DISPOSED" error, but they did not result in an error message in the notebook itself.

3 weeks ago Thanks for the info. Your timing was perfect: the problem just happened again. I believe I may have tracked down more of the specifics for you.
VS Code had been idle for some hours. I sat down and started editing some code, then ran a cell that referenced that code. The error again appeared, in red, below the cell:
notebook controller is DISPOSED. In the logs (with info setting for now):
21:11:05.733 [info] Too many pending requests 1 for kernel 1a6ae5aa-2bea-43c5-b790-ce1eb53017ab, waiting for it to be ready.

...This time the cause is that my edit introduced an (unintended) infinite loop. So, when I ran cell A, Python went into a loop. However, expecting that the code would execute immediately, I also ran cell B. That is when the above error occurred.
The possible parallel with the previous case is that I was debugging, stopped at a break point, when I recognized an issue, changed the code, and ran the cell containing the function in question. Thus, I asked Python to run a cell while a debug session was active.
Indeed, I can now reliably reproduce the error by again executing my code with the bug that causes the infinite loop (cell "A" above), then, while running, execute cell "B". But, only when another condition has also occurred, as explained below.
Next, I changed the log setting as requested, restarted VS Code and repeated the above scenario. This time, no error.
So, that brings us to one additional factor. Issue VS Code Issue #24364 describes my attempts to deal with an upgraded Python interpreter. In both sessions where the failure occurred, I configured a Python virtual environment by hand, then chose that environment in Jupyter. What reminded me of this was that, in the prior session (alas, now gone, so I can't copy the log lines), I saw Jupyter logging messages that it had detected the change in kernel.
To test this, I again went though the steps in VS Code Issue #24364 to select the recommended interpreter (so that the interpreter changes), then to manually configure my virtual environment. As described in that other issue, Jupyter "lost" the kernel when I switch to the recommended one, then "remembered" the kernel when I switched back to my virtual environment. I then reran the required code cells in my notebook, including the one with the buggy infinite loop (cell "A"). As before, with that cell running, I ran cell "B" and again got the notebook controller is DISPOSED. error. Thus, the error concerns:

2 weeks ago As requested, here is a session with full logs and new notebook.
I was earlier wrestling with getting the Python extension to find my virtual environment. After realizing that the documentation was incomplete, and taking the necessary steps, my virtual environment now does appear in the Python: Select Interpreter list. So, the part of the description about Select Kernel not finding my environment is moot. This issue is about the DISPOSED error, the interpreter issue was a confounding factor.
Also, as requested in another issue, I did update the Python extension to the newest version, so the following description is with the latest version.
To start, let's just set up the kernel:

2 weeks ago Now we can move onto reproducing the actual DISPOSED error. As it turns out, I cannot reproduce it once I stopped using the Venv Folders setting to configure my virtual environment, and instead used Venv Path. In a new Notebook:
def loop():
while True:
passloop()x = 10 inside the function.The logs indicate no problem. Recall that this is simplified version of the scenario described in this bug. With a properly-configured interpreter, the DISPOSED error does not occur.
I don't have the time to repeat this using the broken Venv Folders setting, but I'd bet that the problem is due to the use of that setting.

2 weeks ago To see if the use of Venv Path fixes the original problem, I reopened my project. The Jupyter logs contained no error, but it does contain the following odd line:
12:32:22.767 [debug] Refreshed Environments
12:32:22.772 [trace] Python API env change detected, update => '/home/~/pyenv/3.12/bin/python'What is odd is that /home/~/pyenv/... is not a valid Linux path. A valid path (before expansion) would be ~/pyenv/... or (after expansion) /home/paul/pyenv/.... Maybe this is just a cosmetic issue: the rest of the logs look clean and things do work.
I then recreated the infinite loop mentioned before. (The code had since been fixed.) I then recreated the scenario described above. No errors appeared in the notebook or in the logs.
My conclusion is that the DISPOSED error was a side effect of the evil Venv Folders setting. As I suggested in the other issue: do not use this setting. Use Venv Path instead and life will be much easier.

2 weeks ago Than you for getting back, closing this issue as its been fixed
Type: Bug
A notebook is open with a Python kernel. I was working on code for some hours. Nothing particularly special or large: just a around 20 cells, a few hundred lines of code, some Markdown and one MatPlotLib chart. Edited a Python cell containing a function declaration and ran it. Got a red error under the cell that says:
The one thing I did wrong is that I edited the cell and ran it while a debug session was still active on that same cell. Usually this just redefines the function (which, obviously, is rather goofy on my part), but usually if I make this mistake all is fine when I end the debug session. This is the first time I've seen the above error.
There does not seem to be permanent damage. If I end the debug session, rerun the function definition cell and continue working, it seems that things are back to normal. So, this is some temporary glitch that can, apparently, be ignored.
The word "log" in the message above is a link. Clicking on that opens the log with the following:
