npm run android hangs on 'Loading dependency graph, done' (BlueWallet)

I'm trying to clone BlueWallet from this github source.

I clone the project and installed the required packages. Also, the emulator is running with android studio AVD.

But whenever I try to run npm start android it hangs on text Loading dependency graph, done. and nothing more will happen!

it's weird because whenever I try to run the same scenario and commands to start a pure react-native connected to emulator it works with no problem.

the result for npm start android is as follow:

$ npm start android
