System suddenly crashing with exit code 78

Hi all

I'm using a 2017 15inch MacBook pro and every once in a while, it just suddenly dies. Just...BAAM... black screen, no warning and no messages when I turn it back on. It happens when both plugged in and not plugged in.

I've gone through the system logs in the Console app and these are the logs at the time of crash:
