I have the following core packages:

IPython : 8.30.0
ipykernel : 6.29.5
ipywidgets : 8.1.2
jupyter_client : 8.6.3
jupyter_core : 5.7.2
jupyter_server : 2.15.0
jupyterlab : 4.4.1
nbclient : 0.10.2
nbconvert : 7.16.6
nbformat : 5.10.4
notebook : 6.1.5
qtconsole : 5.6.1
traitlets : 5.14.3

And, when I try to plot something with "%matplotlib widget", it simply yields "Loading widget...". My console gives a ton of errors, among which:

Plugin '@lckr/jupyterlab_variableinspector' failed to activate.

TypeError: No provider for: @jupyterlab/application:ILayoutRestorer.

Plugin '@lckr/jupyterlab-variableinspector:consoles' failed to activate.

TypeError: No provider for: @jupyterlab/application:ILabShell.

Error: Could not create a model.

Uncaught (in promise) Error: Module @jupyter-widgets/base, semver range ^2.0.0 is not registered as a widget module

I have spent hours trying to troubleshoot this with ChatGPT, but alas the problem remains. Can anyone help?
