Corona 5 spinning ball of death mac and win

It always happens when trying to render a region or just render in the viewport. Rendering is the VFB never is a issue.
But there isn't a specific reason it seems that causes this. It could work 10x and then freezes or sometimes when I just open the file and press render it freezes straight away.

I too am experiencing this issue with my scene. It gets stuck on the "Computing sec. GI". The time just keeps increasing, but never actually finishes and I have to force quit C4D.
