After deployment of project mouse controlls aren't working

Hello.

In editor I can look around with my mouse and use keys on my keyboard properly. After I package game all controls bind to my keyboard are working but I can’t look around using mouse. Charakter is looking in front of itself. Where is the problem?
The same problem is with “first person template”.

Update.
I just noticed that I can look around only when I have cursor displayed and move mouse with any of the mouse buttons pressed. What ma I missing?
