We're running into an issue in our app where we occasionally get the error "Signal 11 was raised (null)". We have an ARSession where we run predictions on keyframes with our CoreML model. It looks like it's ultimately dying on a call to bool CoreML::vectorizeMultiArray<float, double>. Has anyone run into this before?
We're running on an iPad Pro (4th generation)
