Updated ComfyUI about an hour ago and now its using more Memory than it has ever done

For some reason, after updating ComfyUI about an hour ago I am getting windows ran out of memory

Checking task manager, the python app is using more than 60% of my 64gb of memory

And this is on idle after running a WAN generation

Only goes back down if I restart ComfyUI, but happens again with any type of prompt being run

Something is not right, nothing else has changed on my system apart from the ComfyUI update
