Help() crashes when given name not found

On Win 10 in 3.11.4, 3.12.0b1, and main compiled yesterday, there is a regression in that help() crashes.

help> xyz
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "F:\dev\3x\Lib\_sitebuiltins.py", line 103, in __call__
    return pydoc.help(*args, **kwds)
           ^^^^^^^^^^^^^^^^^^^^^^^^^

    self.help(request)
  File "F:\dev\3x\Lib\pydoc.py", line 2062, in help
    elif request: doc(request, 'Help on %s:', output=self._output)
                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "F:\dev\3x\Lib\pydoc.py", line 1786, in doc

    object, name = resolve(thing, forceload)

  File "F:\dev\3x\Lib\pydoc.py", line 1746, in resolve
    raise ImportError('''\

>>>

In 3.10.11, 3.9.13, 3.8.10, there is no traceback. The exception is caught, the message printed, the short instructions printed, as above, and the help prompt given again.

This somehow messes up IDLE calltips, #105689, but I am treating that as a separate issue, though a diagnosis there as to whether the post-crash IDLE problem is in IDLE itself or somewhere else might give a hint here.

Thanks, I should have checked, or remember commenting there.
