Error during rendering - never encountered this before (log included)

Ulysses0302

I was rendering a simple Iray scene (1 G8M, hair, clothes) in the "Window Seat" set with the standard dome as light source. Then after half an hour  of rendering, Daz suddenly stopped. I was unable to save the render though it looked okay (the temp folder was empty) and the viewport remained black, later, Studio crashed while closing. The log file said what follows below, alas, I am unable to read anything out of this. Was this a random bug? I never encountered any issues with Studio before. Even with much bigger scenes.

I've got no idea what may have caused this, but you're not the 1st one having this problem....

Thanks, I'll check into that. I had found other threads with that issue but none of those got resolved so I thought it might be something unique which only causes the same error message in each case. I used some items I had never used before in that scene to set up some clutter on the shelves of the "Window Seat" maybe one of those caused the issue since I had used the G8M character several times before.
