When you send emitSignal, the app stops

Question

If you keep sending emitSignal at 30 frames, the app will stop. The same is true for slower. You don’t need to create a function in Kodo Engine to receive data to cause the app to stop.
If I comment out this emitSignal, the app doesn’t stop.
Is there any way to replace this part?
I want to get real-time data from Android and render or process it in Godot Engine. I want to know if it’s possible!

val imageAnalyzer = ImageAnalysis.Builder()
                .setOutputImageFormat(ImageAnalysis.OUTPUT_IMAGE_FORMAT_RGBA_8888)
                .setBackpressureStrategy(ImageAnalysis.STRATEGY_KEEP_ONLY_LATEST)
                .setTargetRotation(Surface.ROTATION_0)
                .build()
                .also {
                    it.setAnalyzer(cameraExecutor, object : ImageAnalysis.Analyzer {
                        private var lastEmitTime = 0L
                        private val EMIT_INTERVAL = 33 

                        override fun analyze(image: ImageProxy) {
                            val currentTime = System.currentTimeMillis()
                            if (currentTime - lastEmitTime >= EMIT_INTERVAL) {
                                val width = image.width
                                val height = image.height
                                val buffer = image.planes[0].buffer
                                val data = ByteArray(buffer.remaining())
                                buffer.get(data)
                                emitSignal("updateData", data, width, height)
                                lastEmitTime = currentTime
                            }
                            image.close()
                        }
                    })
                }
