RPR 3.1.0 crash on render start

[bzn7]

I'm having trouble to find cause of crash. I have a quite heavy scene. With this scene, while starting render, right after scene initialization finishes blender crashes. I couldn't find any crash log on Windows temp folder. How can i detect problem?

I created an example of issue. It is probably related to face count.

I will re-create the issue with another scene. I think it is related to object/face count. Disabling random objects solves crash.

I attached a .blend file to first comment as an example of the issue.

so, that's more complex issue and RPR lost a lot of mesh in render progress, and if use user's scene - provide crash
