I am receiving this error VZZOBMFN on App Customization Specialist Superbadge

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: VZZOBMFN

Does that mean I do it all over? Everytime I create a NEW playground it is a NEW username, wouldnt I need the same username to verify everything I have already done?
VinayVinay (Salesforce Developers) 
Yes,  you can create new playgroud org and that should work,  if you do not want to create one then I would suggest you to reach out to trailhead support team and they can help you.

Note: New playground will fix the issue.

Disregard that I disconnected one, but when I created the new it doesnt have any of the work I created under the previous playground.

Unfortunately, new playground doesn't have any previous configurations,  you would need to redo them again here,  As mentioned above if you do not want to use new playgroud log a case with trailhead team and they can help you.

Please mark as Best Answer if above information was helpful.

UGHHHH I spent most of the day working on that, I did log a case with Trailhead.

Hi, It not a big issue you have to creat a new playground. Sometime you will have to create new playground regularly when the system don't pitch you ip. As for fb messenger mod apk (https://freezapk.com/messenger-mod-apk/) we regularly making the new playgrounds and doing our task continue. Because still we don't have found the actuall reason of the issue and the solution of the issue.

The "VZZOBMFN" error code is not a commonly known error, and without additional context or information it is difficult to determine what the issue may be.
I suggest you review the error logs and messages associated with the error, check any related documentation or known issues minecraft (https://minecraftapk.club/), and see if there are any updates or fixes available. If the issue persists, consider reaching out to the vendor or technical support for further assistance.
