Solution:-
1.) Make sure that in IIS Web Server there are no website hostings set up like "Site #586" or "Site #265" - anything with the # symbol followed by a number. These are partially created website hostings that may cause issues with Helm. If there are website hostings like this, delete them from IIS Web Server (right-click the website hosting and choose "Delete").
2.) Go to:

C:\Helm.Config

and delete the IIS.xml file.

Now try and delete or create the domain you were previously having issues with.
