Photoshop failed in NTDLL which shows Photoshop was trying to use some windows feature. Make sure all you device drivers for all your printers are the latest version. Even if you are using a network print the printers device support is installed into you Windows system. Also your Display drivers it may be something to the Print preview for all I know.
I'm on a network. I'll have IT look into it.
Found the solution.
The crash is due to a corrupted preferences file in Photoshop.
You can either uninstall PS including your preferences or you can make PS recreate a new preferences file.
This can be done by pressing Ctrl+Alt+Shift immediately after starting PS.A pop up window wil appear asking you whether you want to recreate your preferences file. Click Yes and problem solved.
CuriouslyPS seems to have this issue since the 2015 version....
