I do apologize for the issue you're having. I'm wondering here if the patch may have not installed correctly and that's part of the issue that we're having here. I would recommend trying to see if you're able to install a Mondo patch here first to see if we're able to get your Quicken open again, I'll leave steps down below.https://www.quicken.com/support/update-and-patch-20182019-release-quicken-windows-subscription-product
Once you get a chance to try this see if we're able to get further. If not we'll see what we can try next.
