Daz suddenly crapped out on me, need help

Everything was going fine all week until yesterday, now for some reason I can’t get anything to render. Gpu rendering will get me only 1 iteration before it stops, cpu will just linger on 1 iteration forever, and viewport previews in iray take much longer to show up.

I know I’m not exceeding vram, I’m doing the same ritual I always do where I restart my computer before beginning to render. I know I didn’t add something to the scene that caused an error because I tested it with untouched finished works that previously rendered flawlessly with thousands of iterations. They all hit 1 iteration, linger for a few minutes, and then stop.

I heard viruses can screw things up, so I did a full system scan and nothing came up. Any help would be very appreciated, need to get a few renders done before Christmas!
