Thanks for the screenshot, ncgross.
Since you've updated to our latest release and performed a repair of Microsoft Office, I'd recommend checking out the resource my colleague, Rasa-LilaM, provided about QuickBooks Desktop 2019 system requirements. This will help confirm what your computer needs to provide the best user experience. Additionally, the error message recommends trying to restart your device.
When exporting reports to Excel, you'll want to make sure they have less than 256 columns. If there's a greater amount, you can select Advanced and untick the Space between columns checkbox, then hit OK to save your changes.
I've checked our ongoing and solved investigations to see if Intuit's aware of an error message like this when exporting to Excel. Currently, there's no investigation record for it.
I notice you mentioned a repair was run for Office, but there's also some other procedures in that same Repair an Office application article provided by my colleague which go over how to toggle Windows user account controls (UAC) to reset anything that may be blocking the feature from working properly. There's also a recommendation in step 5 (after the repair is completed) to uninstall and reinstall QuickBooks. Definitely try these steps out and let me know how they work for you.
Here's a helpful resource about exporting reports to Excel: Export reports as Excel workbooks in QBDT
