Sorry to hear you are still having the issue.
I have tested on both Firefox and Chrome and could get the IDE to load most of the time. When it doesn’t load on its own, the “refresh” button got it working almost immediately. So, it’s looking like some configuration issues in your browsers.
Configurations you can check, in order:
- Are third party cookies enabled?
- Is JavaScript enabled?
- The IDE usually prints some messages to the browser console. Could you look in there and tell us any message you see?
Thank you for your patience. We await your feedback.
