Latest release (5.1.3) doesn't work with Jupyter 4.2.0 (latest release)

See original GitHub issue

When I open a notebook, I get this warning in the console:

loaded widgets
manager.js:115 Could not cross validate the widget frontend and backend versions. Error: Timeout while trying to cross validate the widget frontend and backend versions.(…)

Subsequently, creating a widget fails

utils.js:785 Could not open comm  --  Error: Class ipython.widget not found in registry

I installed the packages with Conda (IJulia automatically installs jupyter 4.2.0, then I did Conda.add("ipywidgets"))

How do I go about fixing this?
