How debug C++ GDExtentions using visual studio c++ , breakpoints not stopping

[whiletrue111]

Godot Version

4.2.1

Question

Hey All in short all compiles and runs but breakpoints not getting hit .
Using VC++ 2022 . follow this tutorial

Invoking :
scons -j4 target=template_debug dev_build=yes debug_symbols=yes

all dll’s and lib complied with dev.debug

The launch.vs.json

{
  "version": "0.2.1",
  "defaults": {},
  "configurations": [
    {
      "type": "default",
      "project": "C:\\dev\\my\\godot\\Godot_v4.2.1-stable_win64.exe\\Godot_v4.2.1-stable_win64_console.exe",
      "name": "Godot Game",
      "args": [
        "--path",
        "C:\\dev\\my\\godot\\godotcpp\\test1\\godot-cpp-template\\demo"
      ]
    },
    {
      "type": "default",
      "project": "C:\\dev\\my\\godot\\Godot_v4.2.1-stable_win64.exe\\Godot_v4.2.1-stable_win64_console.exe",
      "name": "Godot Editor",
      "args": [
        "-e C:\\dev\\my\\godot\\godotcpp\\test1\\godot-cpp-template\\demo\\project.godot"
      ]
    }
  ]
}

And do start the scene from the editor
The breakpoint doesn’t get hit
and looks like this :

And when starting only the game im getting :
Error: Can’t run project: no main scene defined in the project.

Looks like total mess , what im doing wrong ?
Thanks

The no main scene defined is related to a new project that hasn’t established a main scene to run.

You should run the editor version first and establish a main scene.
