System Does Not Wake From Sleep After Security Update 2016-004

I recently installed Security Update 2016-004 for 10.10.5, and now my system freezes every time I put it to sleep. When I put it to sleep it appears to sleep as usual, but when I try to wake it up the screen wakes but I'm stuck on a frozen lock screen. I installed the update as I usually do, and only reinstalled audio drivers. The console log following the sleep command shows these messages:
