If you suspect this is an IPython 7.17.0 bug, please report it at:
    https://github.com/ipython/ipython/issues
or send an email to the mailing list at [email protected]

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

I have the same issue

'TypeError' object has no attribute 'tb_frame'

[slerer]

I had the same issue - reverting jedi from 0.18.0 to 0.17.2 solved it for me.
