After Effects may crash when ASUS GPU Tweak II is installed and the On Screen Display (OSD) setting is turned on. The OSD option displays information such as Frames Per Second in an applications window. At this time the OSD function is not compatible with After Effects when previewing a composition.

Workaround

Open the ASUS GPU Tweak II Monitor window and turn off the OSD setting. This should allow After Effects previews to work without crashing.
