@VisAgilis @hadenep big thanks for your reply. Actually, everything what you are mentioning, looks like is correct in my code. I’ve found out that my issue is a bit tricky 
I have already done my splash screen widget and other menu widgets. When I start my game, I launch Set Input Mode UI Only node in my widgets. It blocks any inputs by the way. I’ve figured it out debuging C++ platform. Function FInputModeUIOnly::ApplyInputMode(..)
So, if you are using Set Input Mode UI Only from widget to widget or wherever, don’t forget to turn it off launching Set Input Mode Game Only or Set Input Mode Game and UI Otherwise, inputs will not work for you!
