Thanks for reporting the issue! Could you try to upgrade the jupyterlab and other related package.

pip install jupyterlab --upgrade

upgrade other package may also help

pip install anywidget --upgrade
pip install widgetsnbextension --upgrade

I upgrade the packages above, but It doesn't work.

Does it work in a normal Jupyter Lab (notebook)?

Mar 03 '25 11:03 superstar54

Yes. It works in jupyter lab.

Mar 03 '25 11:03 muxkin

Please also try

pip install ipywidgets --upgrade

Mar 03 '25 12:03 superstar54

If it still doesn't work, please share your package lists.

pip list > packages.txt

I can compare it with mine.

My ipywidgets's version is 8.1.5, and "packages.txt" is below. packages.txt

I tried in another computer(PC2, the computer with trouble called PC1), and it do works in vscode! ipywidgets's version in PC2 is 8.1.5, too. So it must be someone else make it not work in PC1. packages_PC2.txt is below.

packages_PC2.txt

The second file seems to be a binary, and can not see the details.

Mar 04 '25 15:03 superstar54

Yes. It works in jupyter lab.

In this case, the environment should be fine. You could try to upgrade the jupyter extension of the Vscode, or Vscode itself.
