It could be project related. Seems common with projects with heavy clouds. Like cloud-based projects such as the Nebula project(s) shared by that user who I cannot recall off the top of my head, they are extremely heavy taking so long to render. That's the last one I tried. But I can't see how some warped fractals and couple v3s could be wrong themselves more than just computationally heavy inherently
I know others have confirmed random crashes over the decades frequently as well during rendering, and wishing we could resume renders, cause once you do, you often loose a night/days worth of time.
Usually the issues registered by my systems is a kernel power fault (overheating I am sure), and illegal memory exceptions. With my current i9 it's a shame cause I have some best times on the benchmark chart when I tested the system, but can't seem to use TG with clouded projects without overheating.
