Thank you for the feedback when trying to connect with Support. I'm here to help you today so you'll be able to export your reports to Excel seamlessly.
I can see how hard you've tried to perform the different troubleshooting steps to isolate the issue. For the time being, I would suggest following each step provided from this article for additional solutions: Fix export to Excel issues in QuickBooks Desktop.
I also recommend running the Verify and Rebuild tool to check if the issue within the company file you're using. The process self-identifies and resolves the most commonly known data issues within your company file. For your reference, I recommend checking out the instructions from this link: Verify and Rebuild Data in QuickBooks Desktop.
Moreover, I would also suggest getting back to our Support Team. This way, a representative can review the previous case you had and can investigate this behavior further.
