Error Generating Report

Hello, when trying to run a report on used space I get this error:

An error has occurred while generating report File Export: Comma Separated Values (CSV) on data set Used Space Percent. The error is: Report is stuck in a loop - breaking out so other reports can run.

a lot more listed but ends with:
