I am still getting this error: An error occurred while starting the kernel

Things I tried:

  1. setuptools command
  2. updating spyder
  3. Uninstalled everything that had word python in it from Uninstall or change progam panel
  4. Uninstalling and reinstalling anaconda
  5. Reading people's response on how they tried to fix it
  6. Tried not to get frustrated.

This started occurring after I updated the spyder which I shouldn't have, but now I am stuck with the issue. I will share the complete message that's coming up on my IPhython Console screen.

anaconda spyder installation python

The problem is that you have two Python versions installed:

  1. C:\Users\afsan\Anaconda3\
  2. C:\Users\afsan\AppData\Local\Programs\Python\Python36

Given that it seems you want to use Spyder with Anaconda, please remove your second Python version (manually, if necessary). That should fix your problem.
