Is this crash reproducible? Can you supply the _BugReport.txt listed above? How about a verbose logfile? Attaching a scene that always crashes would be ideal for us.
Without more information I'm afraid there's not much we can suggest or do to fix this crash.
Can you simplify the scene while still having it crash? Sometimes while doing this you might even find out what the problem is.
Otherwise you could upload the scene somewhere else, like google drive, and share that link.
I seem to figure out why Arnold crashed that my CPU and RAM kept high clock which made the PC unstable. When I slow down the CPU's frequency of whole cores, this did not happen until now. I hope my case can help you, engineers. Thanks a lot again.
If downclocking fixes the crash, that means there's likely nothing wrong in Arnold and it's the CPU that was generating errors.
