Anaconda navigator not launching, not even through terminal - python

I installed the latest version of Anaconda on my Windows 10. After installing i tried to launch it but it wouldn't launch even after trying several times. I also tried to launch the jupyter notebook and spider shortcut that was created but even that didn't work. So I tried to run it using the terminal and this is the error I recieved:

I also encountered this problem after I uninstalled the Microsoft Visual Studio C++ redistributable. It fixed (DLL error) after I installed Visual Studio 2015, 2017, and 2019.
You can find it on The latest supported Visual C++ downloads

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:

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.

unable to open jupyter notebook using command prompt, tried installing again and again differently

I ran jupyter notebook and I'm getting the following error. Please help!
I checked the conda version, it's working fine. I added paths in the environment variables. I don't know why it isn't working. Previously it worked fine I recently uninstalled it and installed it again.

There can be an issue with the 64bit version of Anaconda, Try these steps:
Install Anaconda 32 Bit for windows.
Add \Anaconda3 and \Anaconda3\Script to Path in Environment variables.
Open Anaconda Prompt and Create an Environment and activate it.
Once you activate the Environment, you will into it. Then write the command JUPYTER
NOTEBOOK, it should run on your Browser.
If that dose not work you can go back and install a bit older version of Anaconda and try doing the same.
Here for more help (:

I've also had this problem, which I solved as follows.
conda uninstall pyzmq (uninstall pyzmq)
conda install pyzmq (reinstall pyzmq)
conda install jupyter (reinstall jupyter)
You need a corresponding version of visual c++ redistribution.

Since I had the same issue I'm doing some Necromancy on this question:
My Solution is more of a workaround then anything else. I assume you are using anaconda since you mention spyder. My problem seems to have arisen form using pip to install pysftp into the anaconda environment. I had to uninstall anaconda, revert to my original python environment and there it worked without any problems.
Since I like spyder I installed it via pip into that environment...works so far

why is my spyder IDE no longer opening

I just closed my spyder IDE on win7 64bit 64bit python2.7 after a long session.
during that last session, I had also installed a couple of new libraries via conda install. maybe that threw things off?
now when I try to start spyder again, the spyder splash screen appears briefly but then spyder doesn't open. if I try to start spyder from the command line, I get the following error:

try this download setuptools from here and install.
