Could you please confirm which version of Lightroom are you using?
Are you working on raw images or jpeg images in Lightroom?
Is it happening with the most recent imported images or all of them?
This is caused by a broken monitor profile.
Calibrate your monitor with a hardware calibrator, this will create a new profile.
As a temporary fix you can set the monitor profile to sRGB with your computer's OS.
updated lightroom cc today it seems to be all images new and old , raw and jpeg
reinstalling at this moment i will check monitor profile when installed
thanks so much just tried this fix and lightroom is back to normal now
