I had jupyter lab 4.0.7 and everything was working great.
I just upgraded to 4.0.9 and now it cannot start. I would love to get some help. I am pretty lost with this error.
I see this weird conflict in the versions of jupyter lab. Is this a problem? (I installed jupyter lab via conda).
% jupyter lab --version
4.0.9
% conda list jupyter
# packages in environment at /Users/roiholtzman/miniconda3:
#
# Name Version Build Channel
jupyter-client 7.4.9 pypi_0 pypi
jupyter-lsp 2.2.1 pyhd8ed1ab_0 conda-forge
jupyter-server-fileid 0.9.0 pypi_0 pypi
jupyter-server-ydoc 0.8.0 pypi_0 pypi
jupyter-ydoc 0.2.5 pypi_0 pypi
jupyter_client 8.6.0 pyhd8ed1ab_0 conda-forge
jupyter_core 5.5.0 py311h6eed73b_0 conda-forge
jupyter_events 0.9.0 pyhd8ed1ab_0 conda-forge
jupyter_server 2.12.1 pyhd8ed1ab_0 conda-forge
jupyter_server_terminals 0.4.4 pyhd8ed1ab_1 conda-forge
jupyterlab 3.6.6 pypi_0 pypi
jupyterlab_pygments 0.3.0 pyhd8ed1ab_0 conda-forge
jupyterlab_server 2.25.2 pyhd8ed1ab_0 conda-forge
I see that even when I uninstall jupyterlab using conda uninstall jupyterlab, it somehow survives with the version 3.6.6:
% conda list jupyter
# packages in environment at /Users/roiholtzman/miniconda3:
#
# Name Version Build Channel
jupyter-client 7.4.9 pypi_0 pypi
jupyter-server-fileid 0.9.0 pypi_0 pypi
jupyter-server-ydoc 0.8.0 pypi_0 pypi
jupyter-ydoc 0.2.5 pypi_0 pypi
jupyterlab 3.6.6 pypi_0 pypi
The error when I start jupyter lab is
% jupyter lab

Read the migration plan to Notebook 7 to learn about the new features and the actions to take if you are using extensions.

Please note that updating to Notebook 7 might break some of your extensions.
