I use the crash logs to see what can be causing issues. although I can barely read it, I just send it to the engine guy i work with to tell me how to fix it
I’d get the crashes if I overload my scene too much as well.
sometimes it’s a specific shader, or a setting that I have on that can dive the engine. too many objects,
or if I’m rendering too many passes at once in EXR export. I just do one pass at a time for stability.
my scenes can have vastly more everything that you have in yours but my computer is also pretty high gaming spec comp
