Unable to open Anaconda - python

Was working with PyQt5 and suddenly Anaconda crashed and now I am unable to open Anaconda Navigator or Spyder. I was using Anaconda3. I installed PyQt5 using pip and in the Anaconda prompt itself.
This is the error I am getting.

jupyter notebook python compatibility

I am totally new to Python/Jupyter notebook.
Using Windows 11. I installed latest version python Python 3.11.1. Also latest Anaconda - conda 22.9.0.
My jupyter notebook (installed by anaconda) does not start from command line:
jupyter notebook
Traceback (most recent call last):

Conda documentation states "Anaconda supports Python 3.7, 3.8, 3.9 and 3.10. The current default is Python 3.9."
Should I just downgrade my python to 3.9 or 3.10 (I dont care) ?? Any other work arounds?
Updates
Could open the jupyter notebook from the conda prompt. Not stated using it yet. So lets see. If python compatibility issues need to be resolved - need to figure it out.
But, cant start the anaconda-navigator. When I try start from windows start menu - does nothing. From Conda prompt: I get the flwg error on the prompt: >anaconda-navigator Traceback (most recent call last): File "C:\apps\anaconda\Scripts\anaconda-navigator-script.py", line 6, in <module> from anaconda_navigator.app.main import main File "C:\apps\anaconda\lib\site-packages\anaconda_navigator\app\main.py", line 19, in <module> from anaconda_navigator.app.start import start_app File "C:\apps\anaconda\lib\site-packages\anaconda_navigator\app\start.py", line 15, in <module> from qtpy.QtCore import QCoreApplication, QEvent, QObject, Qt # pylint: disable=no-name-in-module File "C:\apps\anaconda\lib\site-packages\qtpy\QtCore.py", line 15, in <module> from PyQt5.QtCore import * ImportError: DLL load failed while importing QtCore: The specified procedure could not be found.

You just need to do this step
pip uninstall pyzmq
and after that
pip install pyzmq
go back to your anaconda-navigator and try to launch Jupyter lab and it'll work fine

Neither Anaconda Navigator or Jupyter Notebook will open

I recently installed Anaconda on my Mac (running OS X 10.8.5), and I'm having several errors:
(1) When I try to open the Anaconda Navigator from the anaconda3 folder, the icon displays on my Dock then quickly disappears.
(2) When I use the command anaconda-navigator in terminal, it displays this error message:

I'm not sure if these issues are related or not, but I decided to post all of them just in case.
