I am having the same error. The issue was originally caused on my Lenovo Y50-70, and GTX 860m, because I installed some new drivers trying to get stable diffusion to run better. Instead, now everything is glitching. Nothing seems to run properly, the CPU maxes out and the GPU doesn't seem to respond or work. OBS for example lags so heavily and crashes and will not encode - just records a blank black or green screen with corrupt meta data. This is true even though I have enabled the gpu in nvidia manager, and also enabled in device manager. I installed the original drivers from Lenovo but didn't work. I'm angry at myself because my restore points (shadow partitions) didn't work for some reason, so I couldn't just roll back.
