Update: It has been working fine with a new shortcut for a couple of weeks. But now, it is doing the same thing to a different company file that I didn't need to open until now, even with no shortcut. I was able to open this file just fine, set up bank feeds (they had most connectivity during a version upgrade), and make a backup with no trouble at all. Then, BOOM this same nasty bug starts up. 

I have opened it from the File Explorer and by just double clicking and by "Open With Quickbooks File Launcher", and it is still doing it. Not sure what is going on here.
