An activity somehow works but is not visible

Question

I am currently working on modifying an existing app. Everything worked perfectly before and I have no idea what went wrong. Basically:

When you start the app there's a splash screen
After 2 seconds there's a login screen
After you log in there should be a main screen but apparently the app turns off

What is happening:

Splash.java - after 2 seconds it starts MainActivity

public class Splash extends AppCompatActivity {

private final int SPLASH_DISPLAY_LENGTH = 2000;

@Override
public void onCreate(Bundle icicle) {
 super.onCreate(icicle);
 setContentView(R.layout.splash_screen);

 new Handler().postDelayed(new Runnable(){
     @Override
     public void run() {
         Intent mainIntent = new Intent(Splash.this,MainActivity.class);
         Splash.this.startActivity(mainIntent);
         Log.e("Splash", "startActivity");
         Splash.this.finish();
         Log.e("Splash", "finish");
     }
 }, SPLASH_DISPLAY_LENGTH);
}
}

MainActivity.java - apparently it works correctly - I put log messages in here and Logcat tells me that methods are running and setContentView is working as well.

@Override
protected void onCreate(Bundle savedInstanceState) {

 Log.e(TAG, "main activity: " + "onCreate");

 startTimerService();

 //LanguageHelper.onAttach(this);
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 //setVisible(true);

 Log.e(TAG, "main activity: " + "setContentView");

 initUI();
 Log.e(TAG, "main activity: " + "initUI");

 androidx.appcompat.widget.Toolbar toolbar = findViewById(R.id.toolbar);
 toolbar.bringToFront();
 Log.e(TAG, "main activity: " + "toolbar");

 if(firstRun)
 {
     //YOUR FIRST RUN CODE HERE
     //int i  = RfidReaderSingleton.getInstance(this).RestoreFactory();

     //////////////////////////////////
     //checkCredentials();
     /////////////////////////////////

     checkForUpdates();
     checkBluetooth();
     //tcp_buttonToast.makeText(getApplicationContext(), "FIRST RUN: " + i, Toast.LENGTH_SHORT).show();
 }
 firstRun = false;

 Log.e(TAG, "main activity: " + "firstRun" + firstRun);

 showPhoneStatePermission();
 Log.e(TAG, "main activity: " + "showPhoneStatePermission");

}

CheckCredentials is responsible for opening logging screen and this part works as well.

@Override
protected void onResume(){
    super.onResume();
    sendMessage(MSG_HIDE_WAIT, null);

    //ToDo
    checkCredentials();

    //GRID
    InitTest(this);
    Log.e("MainActivity", "InitTest");
    //GRID
}

private void checkCredentials(){
    UserModel userModel = DBUserAdapter.getInstance(this).userOperation.getUserModel();
    if(userModel.isRemembered()){
        if(!userModel.isLicenseActivated()){
            Toast.makeText(getApplicationContext(),
                    getText(R.string.logging_result_401) , Toast.LENGTH_LONG).show();
            Log.e("We'startLoginActivity", "1");
            startLoginActivity();
        }
        if(userModel.getToken().equals("")){
            Log.e("We'startLoginActivity", "2");
            startLoginActivity();

        }
    }
    else{
        if(!userModel.isUserStillLogin()){
            DBUserAdapter.getInstance(this).userOperation.cleanUserModel();
            Log.e("We'startLoginActivity", "3");
            startLoginActivity();
        }
    }
    DBUserAdapter.getInstance(this).userOperation.updateLastLogin();
    HttpUtils.SetToken(userModel.getToken());
}

 private void startLoginActivity(){
    mStartForResult.launch(new Intent(this, PlatformLoginActivity.class));
}

After a correct log in the PlatformLoginActivity is finished and this is when the problem happens. The app just kind of turns off but theres no error in Logcat - no message. The MainActivity that was created after a SplashScreen successfully (because MainActivity is responsible for opening PlatformLoginActivity ans this happened correctly). When PlatformLoginActivity finishes the MainActivity is not visible, app turns off but the toastmessage that belongs to MainActivity is visible in the screen.

I have never before seen such a behavior and I have no idea what may be the problem - I tried to log what is happening in the app but apparently it works.

Any help would be highly appreciated as I have no idea what to do.
