I just created an account here to come post the same thing, second bluescreen I get because of this "fairplayKD.sys" file, I've already added it as an exception to my anti-virus, but it didn't help. I've noticed that everyone with this issue is using Windows 10, it might have something to do with the Fall Creators Update, I just hope there's fix for this, because I've just lost all my configurations I had in MTA.
