Arduino Zero debug error with IDE 2.0

Development Tools IDE 2.x
5

Thank you very much.
But for me, some work but some do not.

Here is another problem.
For the sketches unable to debug has an empty launch.json
when I press the "Open launch.json" button in debug panel.
Of course, after I renamed the sketch.
It looks like this:

{
  // Use IntelliSense to learn about possible attributes.
  // Hover to view descriptions of existing attributes.
  "version": "0.2.0",
  "configurations": []
}

"launch.json" is not an auto-generated one?
Is there any way to set up manually the content of launch.json?
