F11 StepInto just goes to next line in VSCode DEV 1.93.0

I am trying to follow the https://github.com/microsoft/vscode/wiki/How-to-Contribute
steps to Build, to Run, and then to Debug.
I built into C:H_Paulvscode1930 It has product.json “nameShort”: “Code – OSS”
and package.json “name”: “code-oss-dev”, “version”: “1.93.0”,

My app (Pencil) has package.json with “main”: “index.js”, part of index.js is

BP1 L90    var mainUrl = "file://" + __dirname + "/app.xhtml";
BP2 L91    mainWindow.loadURL(mainUrl);
BP3 L92    mainWindow.show();

I then enter BP (breakpoint) on those lines.
When it breaks at Line 91, I want to F11 StepInto vscode1930
and then F10 single step to see whats happening to the app’s source code

But F11 just continues with Pencil Line92.

Below are launch.json-s for vscode1930 and for Pencil:
