AttributeError: module 'builtins' console reports failure after any input

I've read previous posts about this issue, which I suspect is a configuration error of some kind.

I installed python 3.13 with a venv, works fine running from python

I can also run from within PyCharm (latest rev 2024.3.1.1 (Professional Edition))

If I set a breakpoint and then attempt to interact with the interpreter, I get the following output (some suppressed, shown as ellipsis)

Traceback (most recent call last):
 File "/Applications/PyCharm.app/Contents/plugins/python-ce/helpers/pydev/_pydevd_bundle/pydevd_console_integration.py", line 85, in get_code_executor
   code_executor = getattr(__builtin__, 'interpreter')
AttributeError: module 'builtins' has no attribute 'interpreter'

During handling of the above exception, another exception occurred:
Traceback (most recent call last):
