Almost lost my drone

I was flying my drone and taking some pics of seawall cliffs, next moment saw error message on remote and when I looked back at where drone was, it was gone!!!!

looked at screen and just saw a black screen!!!! error was something about controller, but replay doesn't show anything.

i tried to follow via map but gps was about 5m in wrong direction. i looked over clips but it was luckily in bushes behind me. is there a way to retrieve the log files?
