Getting this error when I am attempting "Create Reports and Dashboards for Sales and Marketing Managers -> Vizualize Your Data" Module

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: KVRICQRK

Above is the error

I believe you do not need developer edition to be able to do this module..
I have just tried switching to another playground and I was given a different error which told me that Sales Rep Report is missing in the folder...
I do not wish to redo everything again on my other playground..
