Hello, @Jacky Z.
Let me share some information to ensure that you're able to launch QuickBooks on your device.
Just to clarify, are you perhaps using the QuickBooks Online desktop app? If yes, let's try resetting your app's data to isolate your concern.
Here' how:
- 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.
If the issue persists, I suggest contacting our QuickBooks Customer Care so we can further check on the root cause of this unexpected behavior. In the meantime, you can access your QuickBooks Online account using the regular browser. You can use this URL: https://qbo.intuit.com.
Also, you can use this article to help maximize your resources about utilizing QuickBooks and managing the app: QuickBooks App for Windows and Mac: General support.
I'm just a post away if you have other questions about navigating around QuickBooks. Take care and have a good one!
