Photoshop 2017 and 2015 are both hanging on Windows 10 whenever I do anything in camera raw on an image that was taken with the Nikon D850 and then converted to DNG format with the updated converter. Has anyone seen this or have a resolution? This is part of my workflow so I'm dead in the water at this point. I need to kill the task. It looks like one CPU is pegged so I assume that the application is in an infinite loop. I waited for hours and the application has never become responsive again once in this state.
Some people have reported an issue with Photoshop freezing when using Camera Raw. Try going to Photoshop Preferences > Camera Raw (bottom of the menu) and unchecking "Use Graphics Processor". That often resolves the issue.
If that doesn't take care of it, are you updated to the most recent version of Camera Raw?
