Seems it was (most of it?) something about the game messing up two identical items (Slightly worn Bone spears?) doing something with one of them affected the other in some way, and any further attempts with them caused the game to crash.
Yes, the game did load fine.
Yes, bugsplat did load, but I did not report anything. (I do assume that something that show up within the first few minutes, is already known.)

I tried a second game, it was very short. Got killed during sleep. A bit disappointing to not wake up while being attacked, and it was from full health.

A third try. Got quite quick through the first part, and then things stopped in a strange way. I was curious to see what happened when starving to death, which resulted in that there suddenly was no limit to stamina. I did try to sleep anyway, and death occurred during sleep.
But the in game time did keep running, and thus the numbers at the score screen kept changing! With the final score jumping up and going down - I did let it run for a little while, and over all it seems the score rises slowly while being dead.
