Butterfly removal and re-installation

upon receiving multiple errors in Butterfly, including Windows Errors
BlockMesh + Windows Error and, upon fixing these, the most random ‘Indentation Errors’ for a file (case.py) whose indentations I never amended, I am trying to remove Butterfly and re-install it completely.

Can you please help me understand what the uninstallation steps should be ?

I have the same problem and I hope someone could help.
