Nvidia has released the 440.97 Game Ready driver On 2019.10.22, which have fixed the issue that will cause iClone 7 and CC 3 to crash while launching. However, the Studio driver have not update yet. For users who use Studio driver, might want to switch to the 440.97 Game Ready driver, or wait until the next Studio driver release.
Since this fix was made in the driver level, no iClone or CC updates are needed. Thank you for your patience to wait for such a long time.
