Presets make image Red or Black

[Api]

I need advice on a Lightroom problem?
Suddenly all Present makes the pictures completely red or black?
They worked fine before, but now for a couple of days they don't anymore!
I have already reinstalled Lightroom a couple of times, but it doesn't help!
I did the same for Presents!

The first step is to try to reset the Lightroom preferences.

It's recommended to backup your preferences before you reset the preferences to the default settings:

If this doesn't help try is to switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue. 

Go to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor" > Restart Lightroom.

If this doesn't help we need more informations about your environment. 

Which operating system do you use? 

Which version of Lightroom do you use? 

Please post the exact version and not only phrases as "recent", "latest" and so on. 

Please provide also a copy of your 'System Info'. This can be get from the LrC Help > System Info menu item. 

There's a copy button in the System Info dialog. Press this button and paste the info into your next forum post. 

What has been changed on your system before the error occur? Do you have install patches or updates or so?
