Reproduction Steps

OS X 14.1 Sonoma
VSCode 1.85.2
Chrome

Follow the instructions for Debugging/Developing Language Support

npm install Then run "Monaco Editor Playground"

The build is successful, the playground opens but the preview window has a permanent spinner.

The Console in VSCode shows the following error:

Loading "monaco-editor-core" failed

### Actual (Problematic) Behavior

Steps described in documentation lead to an unusable playground

### Expected Behavior

Ability to debug monaco language support locally

### Additional Context

Likely a permissions issue trying to load a local script from a remote domain. 

Start with the Debugging/Developing Language Support section in CONTRIBUTING.md and follow its npm install and “Monaco Editor Playground” steps on the reported OS X, VS Code, and Chrome setup. Inspect the playground preview and the monaco-editor-core loader error. Done means the documented setup produces a usable preview or clearly documents corrected prerequisites and steps.
