Hi @etechBhavik
Like it says, it has been blocked by an extension in Chrome. Either remove the extension or use Incognito-mode without any extensions.

That is not worked.

@etechBhavik Then use a different browser. The problem is in your browser, so unless you can provide browser console logs that point to a problem with Metabase, then it’s very difficult to help with this.
If you’re using some antivirus, then they might have injected an extension into Chrome and you would have to disable that part of the antivirus.
