Thanks for reaching out to us here in the Community, @TBO.
I appreciate you taking your time performing those troubleshooting steps to get this working. I'm here to share some update about this issue.
This has already been reported as an ongoing issue with QuickBooks Desktop and our product developers are diligently working to fix this as soon as possible. I'd suggest performing the troubleshooting steps provided by @ClayJ as a workaround because there currently isn't an exact time-frame as to when the issue will be resolved.
Also, I'd also suggest contacting our Support Team so they can add you to our notification list. You'll get an email notification from us once a fix is available. I'll also update this post as soon as I get a message from them that this has been fixed.
Here's how to reach them:
2. Choose your QuickBooks product at the upper right.
3. Select a topic.
4. Click on the green button that says Get Phone Number.
Thanks for the patience you put into this. Feel free to reach out to me if you have additional questions. I'm always here to answer them.
