Thanks for joining the thread, @DavidPro.

I want to make sure you're taken care of. May I know the specific error message you get from QuickBooks Desktop Pro company file? Further details you'll provide can help me determine immediate fixes.

In the meantime, I'd recommend following the steps in this article: Fix company file and network issues with QuickBooks File Doctor. This will allow you to download the QuickBooks Tool Hub to resolve common errors in the system.

I also encourage visiting the QuickBooks Desktop Apps site to see some third-party data service that can perform a repair to your 1.9 GB QuickBooks Desktop Pro company file.

In addition, if you're experiencing any performance issues and you wanted to reduce your file size, you may condense the data. Here's a link that provides complete details on how to perform this process: Resolve QuickBooks Desktop performance issues: Manage your data file.

Let me know how it goes or share some details that will allow me to assist you more. I'm always here to help. Have a good day!
