Currently, we have an open investigation about this issue, and our engineers are prioritizing it to fix this as soon as possible. The case code is INV-50729, where users are unable to access and see their clients' files.
In this case, I'd suggest contacting our Care Support Team to inform them that you're affected by this hurdle. From there, they'll attach your account to the investigation case. This way, you'll get an email notification once it's fixed and able to get your client's file for reporting downloaded.
Here's how to reach them:

Please know that our staffs are limited, and cut support hours from Mondays to Fridays from 6:00 AM to 6:00 PM due to COVID-19.
Also, I'd encourage you to visit our Community page to search for topics and learn more tips in QuickBooks navigation. At the lower part of the page, you can select a product and sight some topics like Account management and Advanced accounting articles.
Please let me know if there's anything else I can assist you with QuickBooks. I'll be happy to help. Take care!
