Hello @David Lafferty
Thank you for reaching out on the community and telling us about your issue. I do apologize in the issue you're having. That is odd I'm wondering where exactly the issue is. I believe in this case it might help trying to see on a test file if we have a similar issue. This will give us a better idea of where exactly the issue is. I'll leave steps down below and you can find it on the third step on the article.

Note you'll want to make sure you select direct connect. You can do this by clicking advanced options in the sign in screen.
Once you get the chance let us know what you're able to find out. From there we'll see what we're able to do next.
Thanks,
Quicken Francisco
First thing I'll recommend is to save a backup to revert back to just in case. You can find how to do so down below.

Next we'll try deactivating all of the accounts. You can do so by following the article listed down below.

Once all the accounts are deactivated go ahead and follow the article here on reconnecting the accounts.

Once you've done this let us know if you're able to get your main file back up and running. If not we'll see what we can try next.Thanks,Quicken Francisco
