I'm encountering a "QuickBooks Unrecoverable Error" when trying to open my company file. The program crashes with different error codes each time. It's disrupting my work, and I need a solution to fix this issue as soon as possible. What steps can I take to resolve this problem?

Hi , @sarahmorrison53 
To fix the QuickBooks Unrecoverable Error, start by running the QuickBooks Install Diagnostic Tool to repair corrupted files. If the issue persists, try opening a sample company file to determine if the problem is specific to your file. You can also reset the QBWUSER.ini file by renaming it. Finally, update QuickBooks to the latest release and repair the installation through the Control Panel if needed.
