Installing via conda causes "Plugin 'jupyterlab_dash' is already registered."

When installing via conda (see env.yaml below), and running jupyter lab build, then opening JupyterLab, a pop up appears: "Plugin 'jupyterlab_dash' is already registered."

did you found a reason ? Having the same with pip install, jupiter alerts it on each start

Yes, restricting JupyterLab version solves the problem for me. I've modified this line: - jupyterlab >= 4.0.0, < 5.0.0a0 # preventdashbuild problems, also required by https://github.com/jupyter-lsp/jupyterlab-lsp
