vscode, debug angular, first time, doesn't debug, 2nd time stops at main.js then it's ok

Question

when I launch chrome to debug an angular 17+ app, the debugger does not work. If I refresh then it stops at main.js, if I move forward from there it debugs from there.

here is my launch configuration.

"configurations": [
    {
      "name": "Launch Chrome",
      "request": "launch",
      "type": "chrome",
      "url": "http://localhost:4202",
      "webRoot": "${workspaceFolder}"
    },

And my angular.json. I did have problems with the cache in the past.

{
  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
  "cli": {
    "cache": {
      "enabled": false

            "scripts": []
          }
        }
      }
    }
  }
}

it's vscode V1.86.2

what should I look for?
