Thanks for the report. We don't support Python 3.14 yet as it's not been released, and Python's nogil mode is still experimental, so this isn't too surprising right now. Unless it can be reproduced on a supported version of Python, we'll probably just keep an eye on this on the assumption that it will be fixed in core Python, rather than needing changes in pip.
