Hello, 

as in the subject. `jupyter notebook` crashes in -current due to a
failed import, after an update to the latest python-3.14.8. Details
below. 

$ uname -prsv  
OpenBSD 8.0 GENERIC.MP#92 amd64

$ python --version
Python 3.14.8

$ jupyter notebook
Traceback (most recent call last):
  File "/usr/local/bin/jupyter-notebook", line 5, in <module>
	from notebook.app import main
  File "/usr/local/lib/python3.14/site-packages/notebook/app.py", line 18, in <module>
	from jupyter_server.serverapp import flags
  File "/usr/local/lib/python3.14/site-packages/jupyter_server/serverapp.py", line 40, in <module>
	from jupyter_events.logger import EventLogger
  File "/usr/local/lib/python3.14/site-packages/jupyter_events/__init__.py", line 3, in <module>
	from .logger import EVENTS_METADATA_VERSION, EventLogger
  File "/usr/local/lib/python3.14/site-packages/jupyter_events/logger.py", line 28, in <module>
	from pythonjsonlogger.json import JsonFormatter
  File "/usr/local/lib/python3.14/site-packages/pythonjsonlogger/__init__.py", line 11, in <module>
	from . import json
ImportError: cannot import name 'json' from partially initialized module 'pythonjsonlogger' (most likely due to a circular import) (/usr/local/lib/python3.14/site-packages/pythonjsonlogger/__init__.py)

Any hints?

Regards

Enzo Nicosia
