I'm a new guy in the development world, so can you determine where is the problem here?

This usually happens when some code in your app throws an error on launch that causes the app to break. Might be an incompatible plugin, or some other function that is failing at times. Run a debug build and check the console for any errors. You could also post your ionic info output and check if all plugin requirements are met.

Ok, the funny thing. When I added catch block for platform.ready promise - the problem had gone.

    platform.ready().then(() => {

        .....

        console.log('---READY---');
        splashScreen.hide();

    })
    .catch((err)=> {

        console.log('ERROR: ', err);

    });

I hoped to see what cause an error, but my console is crystal clear. I would be appreciated if some one could explain this phenomena.

Thank you.

What you have given isn't sufficient, though have you enabled prod mode in your main.ts? If not change your main.ts to below

    import { platformBrowserDynamic } from '@angular/platform-browser-dynamic'; 
import { AppModule } from './app.module'; 
import {enableProdMode} from "@angular/core";
 enableProdMode();
 platformBrowserDynamic().bootstrapModule(AppModule);
