Anaconda navigator won't launch

Product Help Anaconda Navigator
1

MacOS 12.6
Hi, I am desperate :slight_smile:
It all started with Spyder not opening because of some issue with pyQt.
Following online advice, I uninstalled pyQt, after which Anaconda Navigator stopped launching entirely : the app looks like it’s about to launch, then the icon disappears.
I uninstalled Anaconda from the terminal, reinstalled it and it still won’t work (I also updated my Mac but it did not help).

I tried opening Anaconda Navigator through the terminal using anaconda-navigator, but this is what I get:

Traceback (most recent call last):
  File "/Users/irenebernardi/opt/anaconda3/bin/anaconda-navigator", line 7, in <module>

    import binstar_client

If you have any help, please know I would immensely appreciate it.
Currently I cannot get any work done.
Thank you :slight_smile:
