This can be caused by a defective monitor profile.
Try setting the monitor profile to sRGB (use Adobe RGB if you have a wide gamut monitor).
With Lightroom closed, press the Windows key + R, type colorcpl in the box and press Enter.
Add the sRGB profile, then set it as default.
If this fixes the issue, it is recommended that you calibrate the monitor with a hardware calibrator.
This will also create and install a custom monitor profile that describes your monitor accurately.
