I think this features cleverly uses browser windows instead of standard application windows (which would work without issue).

 

If so, it's probably another issue related to the embedded browser Intuit recently wrote and included in QuickBooks updates - to replace Internet Explorer at the last possible moment, even though MS announced its end of support date over a year ago.

 

It seems to be very error prone and causes crashes as well as the symptoms you describe where buttons don't do anything and/or expected windows don't appear.
