If you have a Nikon D810 then it’s missing the Adobe Standard profile, so here are instructions for copying it elsewhere: https://helpx.adobe.com/lightroom/kb/lightroom-6-1-ignores-the-nikon-d810-adobe-standard-c olor-profil.html
Otherwise try turning on or off the Graphics Acceleration in the CR Preferences.
I'm shooting Canon 6D.. no issue until most recent update...Tried the GPU acceleration already. Thanks!
I am glad I found this and the instructions to copy the Adobe Standard profile.
For several days I have been pulling my hair out trying to work out what was wrong with the images from my 810. Now fixed.
