Flexicontent Error in route.php

Hi, first of all sorry, my English is very bad :oops: .
When I create a module with the latest articles or related articles, that is, when I create a core module of joomla it shows this error:

Warning: Invalid argument Supplied for foreach () in C: \ xampp \ htdocs \ components \ com_content \ helpers \ route.php on line 106

I've seen in the forum there were more people who had the same error and solved it by creating a menu item but I did at first.
I tried installing and reinstalling but always shows the error.

Does anyone know how to fix? Thanks in advance
