I even tried opening from the directory instead of a shortcut. Nada. I got the program to open but it immediately minimized in the taskbar and wouldn't open as a full screen again. So I opened the task manager, right-clicked on the QuickBooks icon under the Apps section on the Processes tab, and clicked on maximize the screen. When the window to open the company file opened I clicked cancel.  This allowed me to have a screen with no company file open. The only tabs available were File and Help. I went to the Help and selected Update. When the update finished I was able to open my company screen in a full window. I believe this problem was caused by a Microsoft update the night before. We have sketchy internet access so maybe the update didn't finish. I am by no means an expert so this fix might not work for anyone but me but here it is anyway.
