Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.60.2 (user setup)
• OS Version: Windows 10 Pro x64

Steps to Reproduce:

1. Click on Debug symbol
2. Click "Run and Debug" drop down
   

Yet my configuration only has

{
  // Use IntelliSense to learn about possible attributes.
  // Hover to view descriptions of existing attributes.
  // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
  "version": "0.2.0",
  "configurations": [
    {
      "type": "pwa-node",
      "request": "launch",
      "name": "Launch Program",
      "skipFiles": [
        "<node_internals>/**"
      ],
      "program": "${file}"
    }
  ]
}

Every project has a mysterious "Run Script: dev"

It is very similar to issue #121148 .
I tried

1. Deleting and recreating launch.json
2. Examined my user settings
3. Deleting everything under C:\Users<userid>\AppData\Roaming\Code\Local Storage
