Anaconda prompt ImportError, conda, and Navigator broken after interrupted package installation

After an interrupted conda package installation, Anaconda Navigator won’t launch, conda returns “not recognized as internal command”, and I get the following error when I open Anaconda Prompt:

Traceback (most recent call last):

Anaconda Powershell returns the same error, with an additional

Invoke-Expression : Cannot bind argument to parameter 'Command' because it is an empty string.

I’ve only tried restarting my computer, as I don’t want to mess things up further. How do I go about fixing this?

Good afternoon,

We are happy to assist you, please uninstall Anaconda with this guide:

Then install it again:
