When I click on Open Designer context menu for workflow.json it fails to start designer and the output is below

@dobxml-0229 Could you share your host.json and local.settings.json files here?

There are a few prerequisites for working with Visual Studio Code and based on the error, looks a setting is incorrect.

Also, support for Azure Functions v3 has ended and you should update to v4. Try updating your Azure Functions Core Tools.

  }
}

sure, see above. I'm on v4.
