Visual Studio Code – "You don't have an extension for debugging 'JSON with comments' " Error when trying to debug VSCode theme

I created and published a VSCode colour theme, using the debug feature to see what it would look like. Now, when I try to debug it, it gives me a "You don’t have an extension for debugging ‘JSON with comments’ error.
I didn’t change anything in the launch JSON file in between it working and now.

launch.json

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Launch Extension",
      "type": "extensionHost",
      "request": "launch",
      "args": ["--extensionDevelopmentPath=${workspaceFolder}"]
    }
  ]
}

I found this question, however, the user solved the problem by just deleting and restarting, which isn’t ideal for me (as I have published it already and want to maintain it).

The accepted answer also suggests closing launch.json or tasks.json, however, the error still persists, even after restarting VSCode.

    This error occurred because I had opened the parent folder of the extension rather than the folder of the extension itself.

    This is the launch.json I use for theme extensions

    {
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch Extension",
            "type": "extensionHost",
            "request": "launch",
            "runtimeExecutable": "${execPath}",
            "args": ["--extensionDevelopmentPath=${workspaceRoot}" ],
            "stopOnEntry": false
        }
    ]
}
