Usually, this error occurs when your data is damaged or corrupted. We can run the Verify/Rebuild tool utility to detect the data damage.
Here's how:
1. Go to the File menu, then hover over Utilities.
2. Select Rebuild Data.
3. On the QuickBooks Information window, select OK. Follow the onscreen steps to save a backup.
4. Let the tool repair your file. It may take some time. QuickBooks may seem stuck, but as long as you can move your mouse, the tool is working.
5. When the tool finishes, select OK.
6. Go to the File menu, and then hover over Utilities.
7. Select Verify Data.
8. Let the tool check your file for data issues.
If QuickBooks doesn't find any problems, select OK. However, if QuickBooks finds an issue with your company file, click Rebuild Now.
Also, make sure QuickBooks has its latest release. This is to ensure that everything is up to date.
