I have figured out the issue with this; it was related to my internet connection, I don't know why. But when I provided a high-speed internet connection, it started working fine.

that's happening due to the fact we haven't yet properly setup a CDN there, so that bundle is being download overseas

Oh Okay Thanks.

BTW you can run the open source playground locally as docker container or node app to avoid connection issues https://github.com/authzed/playground

Alright Thanks.
