Description of the problem
NPM dependency not install, receive CORS error when fetch typings

How has this issue affected you? What are you trying to accomplish?
I am trying to create a demo using a new npm package, but codesandbox is not able to install that dependency. I have tried locally and it works.
To Reproduce
Publish new npm package and use it in codesandbox
Link to sandbox: link (optional)

Contributor guide
First steps

- Comment on the issue to say you are picking it up — it saves two people doing the same work.

Research direction
Start by reproducing the dependency installation failure in the linked CodeSandbox at /src/App.tsx, focusing on the request that fetches the package's typings. Trace the CORS error and verify the published npm package installs successfully in CodeSandbox without the typings request failing.
