  <p>I upgraded the image_picker plugin to the latest version and the first time the app run properly, the second time it gives me this error. So I don't understand if the error is caused by this plugin or by something else. Tell me if I have missed or you need some additional informations.<br>
  Ps. I had to delete some lines of the Xcode's output because of the characters limits, if you need the complete log tell me please.</p>
