Hi there, James Read.
Let's reset the app data in your QuickBooks App to check and verify if it's a data problem.
Here's what you'll need to do:
- Click Help on the navigation bar at the top.
- Select Reset App Data.
- Allow a moment for the process to complete, and then close the app.
- Be sure to right-click the app and Run as Administrator when re-opening.
To know more about this process, I'm attaching a great resource that you can read: QuickBooks App for Windows and Mac: General support.
Additionally, kindly check your app if they met the system requirements for QuickBooks Online.
Let me know how things go by adding a comment below. I'll do whatever it takes to ensure your concern would resolve. Have a great day.
