Hello,
I found a problem
The problem was RAM.
My RAM memory has XMP profiles at 2933 and 3200 MHz. Before Corona 5, on version 4, they worked well. After installing corona for c4d 5, I had to reduce the RAM clock speed, because it was dumping the c4d application from memory (as seen on the links above).
Now I have 2933 MHz on XMP1 profiles on G. Skill Flare X, DDR4, 16 GB, 3200MHz, CL14 (F4-3200C14D-16GFX). And so far everything works.
I think I helped something.
Greetings
Greg.
