Access to script at 'file:///C:/Users/Admin/Desktop/js-constructor/index.js' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: chrome, chrome-extension, chrome-untrusted, data, http, https, isolated-app.

This error message indicates that the browser is blocking access to a script file located on the local file system (file:///) from a different origin (null) due to CORS (Cross-Origin Resource Sharing) policy restrictions.

To resolve this issue, you can try hosting the script file on a web server (using http:// or https://) and access it through a valid origin. Alternatively, you can disable the CORS policy in your browser for testing purposes, but this is not recommended for production environments.

Make sure to follow best practices for handling CORS in your web applications to ensure secure and reliable communication between different origins.
