Mac cannot use jupyter after upgrading to Big Sur

[esther119]

I tried to open my python notebook in jupyter after installing Big Sur but I get an error message. "Python cannot be opened because of a problem." and also said "A connection to the notebook server could not be established. The notebook will continue trying to reconnect. Check your network connection or notebook server configuration." But I'm sure my network connection is good. I updated my python to 3.9 but still didn't work. It only worked in my terminal. I tried to uninstall jupyter notebook and Anaconda, doesn't work too.

Hey @esther119 I was able to launch jupyter with conda=4.9.2, python=3.8
