Here's what I see in the log:

So here's my theory based on my own observations of strange behavior.
I have been landed on a planet before, and in my SRV, when my ship suddenly lifted off all on it's own and simply
hovered a few metres off the ground. I had no option to make it land, only a "dismiss" option.
The game crashed when I hit "dismiss'. I relogged to find myself alone in my SRV, and a recall brought my ship back.
I'm wondering if maybe your ship self-launched, wigged out, and slammed into the terrain a few times which lead to it's demise.
