Gigapixel processing error using CPU, AMD 3900X

Hi folks, I’m getting a pretty consistent “processing error” with Gigapixel v5.8.0. (I have an RX580 4GB graphics card, which I’d rather use, but Topaz products CRASH the video driver (and I need to reboot), even though I’ve upgraded to the latest driver).

Anyway, now I’m getting processing errors using the CPU. The error message directs me to update the GRAPHICS driver, which isn’t even being used, correct?
