问题通常出现在CameraX中使用的CameraFragment或CameraView被恢复时。可以通过在onPause()方法中调用CameraProvider.unbindAll()和在onResume()方法中重新绑定来解决此问题。以下是一个示例代码：

private lateinit var cameraProvider: ProcessCameraProvider

override fun onResume() {
    super.onResume()
    bindCameraUseCases()
}

override fun onPause() {
    super.onPause()
    cameraProvider.unbindAll()
}

private fun bindCameraUseCases() {
    val cameraProviderFuture = ProcessCameraProvider.getInstance(requireContext())
    cameraProviderFuture.addListener({
        // Used to bind the lifecycle of cameras to the lifecycle owner
        cameraProvider = cameraProviderFuture.get()

        // Set up the preview use case to display camera preview in the viewfinder
        val preview = Preview.Builder()
                .build()

        // Choose the camera by requiring a lens facing
        val cameraSelector = CameraSelector.Builder()
                .requireLensFacing(CameraSelector.LENS_FACING_BACK)
                .build()

        try {
            // Unbind use cases before rebinding
            cameraProvider.unbindAll()

            // Bind use cases to camera
            cameraProvider.bindToLifecycle(
                    this, cameraSelector, preview)
        } catch (exc: Exception) {
            Log.e(TAG, "Use case binding failed", exc)
        }
    }, ContextCompat.getMainExecutor(requireContext()))
}
