OBS SVT AV1 hangs the whole computer

OBS SVT AV1 hangs the whole computer. After about 30 minute encode. Specs https://valid.x86.fr/tw2qya There's no overheating or anything. So not sure what's causing the hang, it doesn't happen with any other encoders. The AOM encoder however can't encode fast enough. It doesn't BSOD, the system does recover, except most things are broken until you log out and back in. OOM? But shouldn't be limited. image 3840x2160x30fps nv12
