I found that if you have a laptop and it is running on Intel, for some reason (UE4 and Intel paired up to better “utilize” the Intel core) it will decided to utilize the Intel’s CPU instead of your graphics card. Switch your preferred settings for your laptop’s graphics card to high performance on Battery and Plugged in. I’ve had it working like this for a long time, and haven’t experienced the crash ever again, however I have to keep my laptop plugged in. If the laptop isn’t plugged in, regardless of any settings I’ve messed with, it won’t utilize the high performance graphics card and trying to do anything that would normally be a simple thing GPU wise will kill your Intel CPU and crash the engine.
TLDR: Set your Graphics settings to High Performance on Plugged In/ Charger and always keep it plugged in when working with the Engine.
Hope this helps you guys the same way it helped me.
