android - Stuck after Cropping Image in Gallery Kotlin Crop Image from Gallery

Question

unfortunately I'm stuck again for a few hours. I want to crop an image from the gallery to a certain aspect ratio and paste it into an ImageView. I also want to keep the path of the image in a string. The problem is that the ImageCropper of my gallery hangs as soon as I crop the image. I get stuck on this screen forever. So the cropped image is not passed back to my app.

Here some important parts of the code:

private fun pickImageFromGallery() {
    val intent = Intent(Intent.ACTION_PICK)
    intent.type = "image/*"
    intent.putExtra("crop", "true");
    intent.putExtra("aspectX", 3);
    intent.putExtra("aspectY", 2);
    intent.putExtra("outputX", 640);
    intent.putExtra("outputY", 426);
    intent.putExtra("noFaceDetection", true);
    intent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString())
    intent.putExtra("return-data", true);
    startActivityForResult(intent, IMAGE_PICK_CODE)
}

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)

    if (resultCode == Activity.RESULT_OK && requestCode == IMAGE_PICK_CODE) {
        dev_img.setImageURI(data?.data)
    } else {
        Toast.makeText(
            applicationContext,
            "Vorgang abgebrochen.",
            Toast.LENGTH_SHORT
        ).show()
    }
}

Without the intent.putExtra commands the image is taken directly from the gallery into the app. Unfortunately then not cropped. I don't want to use external libraries with my app, so I have hardly found any solutions on the internet. I hope someone recognizes my problem and can help me to correct it. Thank you.
