Suddenly getting an error when trying to show any Plotly figure in Jupyterlab

📊 Plotly Python

In a jupyter lab notebook that worked well yesterday, suddenly anywhere a plotly figure was shown previously using the code display(someplotlyfigure), I instead get an icon like this:

plotlyjserror

After clicking to show the JS error I get:

I really don’t know what the Error message “Error: Module jupyterlab-plotly, version ^5.23.0 is not registered, however, 5.22.0 is” is trying to tell me and what I can do about it.

This only happens if I use FigureWidget instead of Figure to create the Plotly figure

When I load the package “jupyterlab_plotly” using my environment, it succeeds, but it dos not have a __version__ attribute.
It is definitely not a package I have installed and I did not update my Python packages since yesterday so I have no idea why this would break out of the blue?
