I had this same issue in Chrome with my trial account and my test Starter Portal. When I allowed third party cookies from https://make.powerapps.com/  the issue was immediately resolved. I hope this helps.

Hello Panesh,

 

Sorry to hear you are having issues with loading the Portal Studio.  These issues are typically browser settings or sometimes firewall settings.

 

You can try accessing the Portal Studio using a different browser in-private / incognito mode to see if that helps.  Other option would be to try accessing outside your network.

 

I will provide some links that have general mitigation you can try.  If you are still blocked, I would recommend opening a support case for investigation.

sometimes this can be caused by extensions installed in the browser.. try on an in-private session or temporarily disabling any browser extensions
