While doing Apex customization specialist superbadge challenge Unexpected error took place. I am using fresh Org for superbadge. Reference error Id-XYUEMVGB

Unexpected error while verifying challenge due to pre-existing code in the challenge org. We recommend using a new Developer edition.

But I am using new Org only. Please help me. This happened while checking the challenge of Apex Customization Specialist Superbadge

Getting the same error 
Challenge Not yet complete... here's what's wrong:
There was an unexpected error while verifying this challenge. Usually this is due to some pre-existing configuration or code in the challenge Org. We recommend using a new Developer Edition (DE) to check this challenge. If you're using a new DE and seeing this error, please post to the developer forums and reference error id: TFZJYBAF

Please help!
