VSCode: Debug > Add Configuration, nothing happens

Using Visual Studio Code v 1.32.3 on Windows 10, when I navigate to Debug > Add Configuration, nothing happens. No errors or other messages, nothing appears to be written to the workspace folder, no errors in Event Viewer, so far just nothing.

I am somewhat new to VSCode so please don't discount that this might be a newbie error. Potentially notable is that the project is a Cordova project, I have created a Workspace (and confirmed that I am using it and not just opening the folder).

What I have checked so far:

• Verifying that nothing is actively trying to build or otherwise access that folder. PhoneGap Desktop is stopped and no emulators running.
• Restarted PC
• Reinstalled the Cordova Tools plugin

Interestingly if I open a new instance of VS Code and before opening any file or folder I go back to Debug > Add Configuration I will get a message "Please first open a folder in order to do advanced debug configura..." So this indicates that there may be a problem with my workspace or directory but I haven't found it yet.

Any ideas greatly appreciated.

Edit 1:

Version of Cordova Tools is 1.8.0.

I've since tried adding my own launch.json to the .vscode directory. Contents:

{
    "version": "0.2.0",
    "configurations": [
    {
        "name": "Run android on device|emulator",
        "type": "cordova",
        "request": "launch",
        "platform": "android",
        "target": "device|emulator",
        "sourceMaps": true,
        "cwd": "${workspaceFolder}"
    },
    ]
}

Notable is that in the bottom right corner of the window a "Add Configuration" button appears while I am viewing launch.json and it does appear to work correctly, prompting me with snippets to add.

None of these impact my ability to debug unfortunately.
