Crankshaft Pulley Failure
The area I’m pointing to looks like it happened over some time, judging by the rust in the cracks, until the point that there wasn’t enough attached to to take the force exerted by the belt tension. I’m going go with metal fatigue. Have you checked to see if the part has been superseded to a updated part? A pulley that was not turning true over time could have caused this type of failure. Stuart
