Hi user16058,

You could be experiencing random browser issues. We can do the basic browser troubleshooting steps to get rid of this error.

To start, you'll want to sign in to QuickBooks using a private browser. This step disables its extensions and stops the cache from saving your browsing history.

• Google Chrome: Ctrl + Shift + N
• MS Edge and Firefox: Ctrl + Shift + P
• Safari: Command + Shift + N

If you can export the report as PDF, you can go back to your regular browser and clear its cache. If not, please try other browsers to see if we get the same thing.

Feel free to share an update after doing the steps above.
