For information: I just got the same error after trying to build locally [JupyterLite's xeus-python-demo](https://github.com/jupyterlite/xeus-python-demo). First in my usual mamba forge install. After which my mambaforge got broken: any attempt...

For the record: a `mamba clean --all`, fixed my mamba installation. But the jupyterlite build still breaks.

Good news: upgrading conda to 24.7.1 which contains https://github.com/conda/conda/pull/13962 resolved the issue! ``` mamba install conda==24.7.1 ``` Ref: https://github.com/jupyterlite/xeus-python-demo/issues/39

Just as a data point: I get the same symptoms here: firefox, ubuntu, fresh mamba environment containing jupyterlab, with pip installed jupytercad.

> @nthiery if you felt like rebasing the binder branch onto master, this would be awesome. If not, we'll get around to it eventually. Done! See the PR from the...

Hi @lemuellew; I could not reproduce here; could you try again with the latest version?

Hi @drscotthawley, 1. To edit the rise cell metadata, you can use the property inspector in the right jupyterlab toolbar. This is indeed deviates from the original rise in Jupyter...

Just as a data point: I did not manage to reproduce; with the same jupyterlab 4.0.5 and rise 0.40.0, I can execute cells as expected. Ubuntu 22.04, Firefox, Python 3.11.5
