Hi there, Bkkprgal.

Thank you for visiting again the QuickBooks Community and for providing the exact error you've received. I'll be sharing some troubleshooting steps to ensure you'll be able to select the Share this report option without any issue. Beforehand, may I ask for further details on how you customized the report before trying to memorize it? I appreciate any extra details so I can share the exact steps to resolve the problem.

In the meantime, you'll have to make sure that you run the QuickBooks Desktop as Admin.

Here's how to run as an administrator:

1. Close QuickBooks Desktop.
2. Right-click the QuickBooks Desktop icon, then select Properties.
3. Under the Compatibility tab, choose Run this program as administrator.
4. Hit on Apply and OK.

 Then, update your QuickBooks Desktop to the latest release to keep your software up-to-date so you always have the latest features and fixes. 

Additionally, I also recommend running the  Verify and Rebuild Data Utilities to get this sorted out. The Verify Data utility identifies any potential data damage issues that might've caused getting an unexpected error message. While the Rebuild Data utility repairs damaged data in your company file. Before this, you'll have to secure a backup copy of your company file.

To Verify data:

1. Go to the File menu.
2. Scroll down to Utilities.
3. Select Verify Data.
4. Click OK.

To Rebuild Data:

1. Go back to the File menu.
2. Choose Utilities.
3. Select Rebuild Data.
4. Click on OK when you get the message Rebuild has completed.

For further details, you can refer to this article: Verify and Rebuild Data in QuickBooks Desktop.

Lastly, you may refer to this article to view different available reports in QuickBooks Desktop that the program uses to display data from your company file so you'll be able to see various aspects of your business: Understand reports.

Let me know if you have any follow-ups or other questions about managing reports in QuickBooks. I'm always here to help. Wishing you a good one.
