I'm adding this new crash incident in the hope that it will help. Recently I was having a crash while updating Express Connect+ accounts. That problem just seems to have fixed itself.
Today I was viewing the “Income & Expenses” widget on my “Home” page. I noticed that the expenses for April were not showing up. I then clicked on the Customize gear and tried to open the "Cash Flow" report, from the widget, which led to the crash.
Upon reopening Quicken I went to the “Reports” tab and opened the “Cash Flow" report without an issue. However, the widget is still not reporting all the expenses for April. All other reports, that I tried, are showing all the expenses for April.
I reported this incident to Quicken and am just adding this quirky one to the discussion.
