Generator key not working - File system provider

Using VSCode, Monkey C installed and SDK verified.

Trying to 'Generate a developer key'. For various reasons I first tried to do this on a remote folder and this causes the developer keygen to fail.

I moved the workspace & folder to a physical drive and the old location is stuck somewhere - I can't find in the settings anywhere.

So I get the error 'File system provider for sftp://................ is not available'

Help! How do I move the running folder for the keygen?
