thanks for your answers. I finally solved it by setting the Max Steps to 64 in the Render Setting for Volume.

Hello Patrik, many thanks!
Does anyone know anything else? Or could someone else try rendering the cloud without shadows? I just can´t figure out why it crashes. 😥

i used Cuda but have now switched to Optix, but the same result. If I switch to CPU only, it doesn't crash immediately, but it just stops with "Path Tracing Sample 1/32" just like with GPU Compute, only that it crashes faster. When I turn on the shadows again, it renders without any problems.

I've now done it like this and let it crash. I attached the debug file but I can't find the crash.txt file anywhere 🤔
hmm strange. But Blender 2.93.2 isn´t out yet. Are you using the developer version?
I attached the system info file. But i can´t find the crash logs in the /tmp/ directory or am I doing something wrong here?

thanks for your reply. I have now removed everything from the file except for the cloud and even then the problem occurs if i uncheck something under Ray Visibility.
To recreate the issue, you have just to select the cloud and in the Object Panel under Ray Visibility deselect a tick such as the shadow and then go to the rendered preview.
