After contacting support and going back and forth with the QB Data Services and realizing it's not my company file either, the "temporary" fix which is working for me is the [Alt] key. Before pressing "OK" to load the company file, hold down the [Alt] key on the keyboard then press "OK" and continue to hold that key down  until QB loads the stuff on the left. You'll notice the built-in browser "Home" window doesn't load. That's what's been causing QB to crash. You can click the "Home" shortcut on the left to open that window after QB loads. Until there's a patch for this issue, that's what I've been doing to get around this.
