Flashlight don't works from 4,14 To 4,17

Hi.
I made a flashlight into my project when I was working with UE 4,14. I changed To 4,17 because continuous crashes of 4.14 was making me crazy. In 4,17 my flashlight don’t works. I saw many tutorials but my flashlight is activable from widget and I have not fonund anything. My blueprints are ok and I can’t understand what I am wrong . My project is 99,99% complete but this issue can’t make me finish It. Please help me.
