Nice to have you joined this thread, @lbjreim. 

Several factors are affecting QuickBooks not to open correctly. A couple of them are technical errors that can be caused by the system and environmental problems in addition to how QuickBooks interacts with these variables. 

You can resolve this by connectivity and setup testing. Refer to the following information:

• Download and install the QuickBooks Tool Hub, then run the TLS 1.2 Readiness tool. This will update your operating system to be compliant. See this article for detailed guidance: TLS 1.2 for QuickBooks Desktop for Windows.
• Verify if you've set Internet Explorer as your default web browser. Check out this article for more information on how to do it: Set Internet Explorer to be your default browser.
• Check that you can visit secure websites outside of QuickBooks Desktop, such as your financial institution's sign-in page.

You can also check this link for more details about the process: Update QuickBooks Desktop to the latest release.

If you've already done with those steps and you can't still access your desktop, I suggest contacting our Contact QuickBooks Desktop support. Ensure to check their support hours to know their availability: Support hours and types.

I've also added this link that provides additional troubleshooting steps in accessing your QBDT: QuickBooks Desktop doesn't start or won't open.

Let me know in your reply if you have any follow-up questions about managing your QuickBooks. I'll be more than happy to back you up. Have a great week ahead!
