I originally submitted this issue for debugpy microsoft/debugpy#1623, and saw on a linked issue that there is a comment tracking the issue back to PyDev.Debugger: microsoft/debugpy#1633 (comment)

I'm not sure if the issue is in this repo, but potentially this line is at fault?

Please see the linked tickets for details, but the end result is that I am unable to debug tests in VSCode via the Python extension right now. The following error is raised:

E       matplotlib._api.deprecation.MatplotlibDeprecationWarning: The interactive_bk attribute was deprecated in Matplotlib 3.9 and will be removed in 3.11. Use ``matplotlib.backends.backend_registry.list_builtin(matplotlib.backends.BackendFilter.INTERACTIVE)`` instead.
