If you suspect this is an IPython 7.16.1 bug, please report it at:
https://github.com/ipython/ipython/issues
or send an email to the mailing list at ipython-dev@python.org

You can print a more detailed traceback right now with "%tb", or use "%debug"
to interactively debug it.

Extra-detailed tracebacks for bug-reporting purposes can be enabled via:
%config Application.verbose_crash=True

Hi. Please try to downgrade Jedi and see if the problem persists:

pip install jedi==0.17.2

I think this is the problem that has been fixed in IPython 7.20 (#12793), but it's not available for your Python version. I'll close this for now, as it looks like a duplicate, but if the workaround above does not fix your problem - feel free to ping me here, I'll reopen & try to help you further.
