The resource cannot be downloaded from another source due to the built-in Cross-access Policy (COEP). Resource https://stackblitz.com/headless ?version=1.3.0-internal.10 is blocked.

Steps to reproduce

Additional context

With the Cross-Origin Embedder Policy (COEP) enabled, each resource must specify a suitable Cross-Origin Resource Policy (CORP). Previously, adding CORP headers or using Cross-Origin-Embedder-Policy: credentialless was suggested, but the issue persists.
