When I press tab to complete code or get any hint, the ipython have nothing interaction

When I press Tab to complete code or get any hint, the ipython have nothing interaction, however, I continue inputing my code or I press directly Enter, then the iPython fall crash and output:

If you suspect this is an IPython 7.19.0 bug, please report it at:
    https://github.com/ipython/ipython/issues
or send an email to the mailing list at [e-mail]

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 don’t know the causion of problem whether CPU is AMD(Ryzen 4800U).

TL;DR: Running pip install jedi==0.17.2 inside env with installed IPython did the trick for me.

In fact, wrong signature and of course non-pinning the dependencies…

IPython/core/completer.py:

class IPCompleter(Completer):

    def _jedi_matches(self, cursor_column:int, cursor_line:int, text:str):
        interpreter = jedi.Interpreter(
            text[:offset], namespaces, column=cursor_column, line=cursor_line + 1)

jedi/api/__init__.py:

class Interpreter(Script):

    def __init__(self, code, namespaces, **kwds):
        ...
        super().__init__(code, environment=environment,
                         project=Project(Path.cwd()), **kwds)

class Script:

    def __init__(self, code=None, *, path=None, environment=None, project=None):
        ...

Oh, looks like it’s already in master https://github.com/ipython/ipython/commit/90fb12b53e52314979167098de1c47f75f8fb14e#diff-60f61ab7a8d1910d86d9fda2261620314edcae5894d5aaa236b821c7256badd7 So I hope it will be released soon.
