So, I launch Quicken Classic (latest version), and I was immediately greeted with this (data path blurred for my privacy):

Then Classic opened to a white screen. I immediately went to the File menu, selected the data file from the recent menu, and the data file immediately opened.
I do use a cloud storage provider to save my data file, but I thought that one of things resolved in the latest update was improving how Classic interacted with data files stored on cloud providers. Was I wrong?
