App struck on white screen, only when I generate apk from my local machine

Hi,
My app works fine when I run it on emulator or if I run the app on real device with command ‘ionic cordova run android’. It also works fine, if I generate the apk from the ionic dashboard and install on my device. But if I generate the apk on my local machine using the command, ‘ionic cordova build android --prod --build’, app stuck on white blank screen. What might the problem.
