Ionic App not working anymore

A few days everything was working okay and unfortunately i don`t remember what i did, but now the app is not working as it should. I think i deleted the platforms folder and after adding again the platforms it stopped working. It added Android 7.0.0 and i had to remove it and installed 6.3.0 like before.

Ionic info:

ionic (Ionic CLI) : 4.10.2
Ionic Framework : ionic-angular 3.9.3
@ionic/app-scripts : 3.2.2

I am using - “ionic cordova run android -lc” and there is nothing unusual there. After the splash screen i am getting this error and if i click cancel i can see the LoginPage but if click Login the app should show HomePage (the login process is working perfectly )but it shows the same error and if i click cancel it is only white page. I removed all plugins, but didnt help. I used ionic-cli 4.4.0 before but it is still not working.

I can upload only 3 images:

If i missed some information please let me know.

This is because ionic v4 has changed the lazy loading with the angular routing. See Ionic v4 lazy loading not working after migrating from v3
