The exact same thing is happening to me! I'm using Windows Professional 7 64-bit with 16GB RAM.
I've owned every version of Lightroom available. This has never happened. An earlier version of Lightroom 6.x was working fine. Tonight I started up the application and decided first to do an update. It updated to version 6.1.1.
Now when I go into Develop mode, I can only edit one or two photos before it hangs and I have to kill the process. It happens when I try to go to the next photo, exactly as you say. Sometimes it hangs immediately when I load it, displaying the first photo. Other times I can develop one, two, or three photos. But I can only use the software for a few minutes before it freezes and I have to force the application to close and start over.

Well yes, obviously - it's a bug related to GPU support, which it new to Lr 6/CC 2015.
The answer above still stands - turn off GPU support.
Well, then, Adobe fix it, obviously.
I don't want to turn off GPU support. I want the bug fixed. Sheesh. Why the cavalier attitude for a loyal customer? I don't want buggy software. I don't want this Creative Cloud crap. I don't even want this buggy AAM Updates Notifier.exe that crashes every time I boot into the system, yet there is no way to uninstall it.
Well, yes, obviously instead of releasing more solid products Adobe is getting lazy and putting out cruft.
