  <p>I've looked on the paths of react-native-screens.js, but I found nothing special. But one thing suspicious is that the version of react-native-screens has changed several times. Unfortunately, I don't remember what it was 2 days ago, when it was working fine, and yesterday it was different, and today it changed again.</p>
  
  <p>I also tried to change react-navigation-stack version to 2.1.1, which was working fine, but no luck...</p>
  
  <p>I'm so sorry that this is such a vague question,</p>
  
  <p>Thank you.</p>
