Solution 1: Use the QuickBooks File Doctor Tool

Download and run the QuickBooks File Doctor Tool from the official Intuit website.

Follow the on-screen instructions to install and run the tool.

The tool will automatically diagnose and repair issues related to QuickBooks company files.

Solution 2: Verify File Path and Folder Permissions

Ensure that the company file is stored on a local drive and not on a network drive or external storage.

Verify that the file path and file name are not too long or have special characters.

Check and adjust folder permissions:

Navigate to the folder where the company file is stored.

Right-click on the folder and select "Properties."

Go to the "Security" tab and make sure that the QuickBooks user has full control.

Solution 3: Rename .ND and .TLG files

Navigate to the folder where the company file is stored.

Find the files with the same name as your company file but with extensions .ND and .TLG.

Right-click on each file and rename them, adding ".old" at the end of the file name
