Hi @HappyPolygon, many thanks for your response.
The crashes are very random and now guaranteed to happen at some point each time I open C4D. Most times, it is when I render an animation - after rendering about 10 frames, sometimes less and other times a bit more, the crash happens. Have also had the crash happen while Redshift is compiling shaders/prepping to start the render (after I click the render button).
I haven't experienced the crashes with Standard Render but again, I hardly render using it, but now that you've mentioned it, I will run some tests utilizing the Standard Render and feedback, even though I suspect the issue might be beyond rendering as I have experienced the crashes while busy with other tasks like sculpting or modeling.
Would really appreciate your help.
