The Windows 10 upgrade probably replaced you previous monitor profile with an incompatible profile. Recalibrate your monitor or assign the previous monitor profile to your display
thank you so much !!!!
ok i put RGB 1998 for output !!!!
Adobe RGB 1998 is not a monitor profile and I'm not sure what you mean by "output.". You can assign the Adobe RGB 1998 color profile to a wide gamut display to determine if the current profile is causing the issue. If you have a standard gamut display use the sRGB color profile. Use Windows Color Management as outlined here to assign the profile to your display:
Just out of curiosity what profile is currently assigned to your display? You can also download the display profile for your specific model monitor from the manufacturer's website, but this in fact could be what's causing the issue. I believe Windows 10 automatically assigns an OEM display profile that isn't compatible with LR (probably ICC Version 4).
The best choice is to use a monitor calibrator.
