I recently ran conda update --all to update the Python libraries and my conda is broken. I get the following error on every conda command. Below is the error.
C:\Users\anves>conda update

TypeError: LoadLibrary() argument 1 must be str, not None1 Answer
Not much of a solution... but I just re-installed conda instead of mucking about. This fixed it.
Be sure to back up your envs and other files.
