PhpStorm shows undefined class but I can use this class

Question

I'm creating my first project in Symfony and PhpStorm shows me something like this "Undefined class 'AbstractController'" or "Undefined class 'JsonResponse'". I tried everything I found on Google but nothing help... Do you have any ideas?

I tried below things:

• Invalidate caches and restart
• idea.properties -> change idea.max.intellisense.fillesize=2500 to 5000
• Include path
• CLI interpreter
