Unable to run Embedded Project: Looks like this project is being embedded without proper isolation headers.

Describe the bug

Problem Description

I can't see the preview of the code while trying to embed stack blitz. It says that the issue is related to cross-origin isolation headers, but I highly doubt this is outside our control. I've tried every way, made by the application crossOriginIsolated too but still, It shows the same error.

Steps to Reproduce

1. Open this Stackblitz sandbox: https://stackblitz.com/edit/sdk-create-project-with-npm-ts-lpsajdai?file=index.ts
2. Let it embed & you'll see this kind of screen in the preview:

Please help me resolve this issue.
