Maybe the problem is compatibility with latest ipywidgets version 8.x since 7.6 seems to work on another system.
One system with following does work (note older 7.6.5 ipywidgets version works)
IPython : 8.0.1
ipykernel : 6.9.0
ipywidgets : 7.6.5
jupyter_client : 7.1.2
jupyter_core : 4.11.1
jupyter_server : 1.19.1
jupyterlab : 3.2.9
nbclient : 0.5.10
nbconvert : 6.5.4
nbformat : 5.7.0
notebook : 6.4.8
qtconsole : not installed
traitlets : 5.8.0

But a system with following does NOT work (latest ipywidgets version
Python : 8.10.0
ipykernel : 6.21.2
ipywidgets : 8.0.4
jupyter_client : 8.0.3
jupyter_core : 5.2.0
jupyter_server : 1.18.1
jupyterlab : 3.4.5
nbclient : 0.6.7
nbconvert : 7.0.0
nbformat : 5.7.3
notebook : 6.4.12
qtconsole : not installed
traitlets : 5.9.0

Thanks for filing this issue, IPYWidgets 8 is not yet supported and the plan is to get that fixed for the next release
YOu can test that now

• Please install latest VS Code Insiders
• Open the extensions page, search for Jupyter and click the button Switch to Pre-Release Version
• Similarly please install the latest Pre-Release version of the Python extension

Closing this issue as I believe this has been fixed in the pre-release version (again you need vscode insiders)
If that does not work please feel free to re-open this issue or ping me and I will open this or create a new issue
