EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000200 when adding filter to an image

I am trying to change an image to black and white, these images are supplied from a service call and as soon as I get the image I apply the noir filter to change them to black and white. I have been getting this dangling pointer exception only on iOS 13 the other iOS versions do not have this issue.

This is the code :

extension UIImage {

    var noir: UIImage? {

        let context = CIContext(options: nil)

        guard let currentFilter = CIFilter(name: "CIPhotoEffectNoir") else {
            return nil
        }

        currentFilter.setValue(CIImage(image: self), forKey: kCIInputImageKey)

        if let output = currentFilter.outputImage,
            let cgImage = context.createCGImage(output, from: output.extent) {
            return UIImage(cgImage: cgImage, scale: scale, orientation: imageOrientation)
        }

        return nil
    }
}

Use case: 

var member: Faculty? {
    didSet {
        guard let lecturer = self.member else {
            return
        }

        FacultyService.image(
            atPath: lecturer.thumbnailPath,
            process: { (image: UIImage) -> UIImage in

                if lecturer.Id != nil {
                    return image.noir!.withRenderingMode(.alwaysOriginal)
                }  else {
                    return image.withRenderingMode(.alwaysOriginal)
                }
        },
            success: { [weak self] (path: String, image: UIImage) -> Void in
                guard let strongSelf = self else { return }

                if path == strongSelf.member?.imagePath {
                    self.imageButton.setImage(image, for: .normal)
                    self.imageButton.layer.animate()
                }
            },
            failure: { () -> Void in

        })
    }
}

This is likely to be a compiler or Core Image framework bug.

I would encourage you to file a bug report on Feedback Assistant.

If you look at this thread from the Apple forums, there have been issues like this before and you may just have to wait for Apple to fix it...

There are also others that have encountered your specific error message, How to fix warning "CoreUI: RunTimeThemeRefForBundleIdentifierAndName() couldn't find Assets.car in bundle with identifier: '(null)'"?

You could also try releasing a new version of the app built with the newest Xcode version and hope that the customer in question updates the app and that it solves the problem.
