@avishayil can you check this one please.

This PR only affects windows support which in fact is already broken.

What actually I did different from the old implementation is that the old windows support fully restarted the app instead of only the react native host.

void RNRestart::loadBundle() noexcept {
  auto host = Microsoft::ReactNative::ReactNativeHost::FromContext(m_context.Handle());
  if (host) {
    host.ReloadInstance();
  }
}

The windows support is needed as a prerequisite for this PR on react-native-screens (which depends on react-native-restart) to have a complete implementation.
