Thanks for letting us know about this.
I have found a post the same concern as what you have, please check this link: https://quickbooks.intuit.com/community/Other-questions/I-can-t-get-any-reports-to-generate/m-p/2406...
We will let you know once we have an update. For now, you can try to do browser troubleshooting to check the reports from time to time.
Let me know if you need further assistance. I'm always happy to help!
