Line Trace by Channel issue

Hi everyone, I recently started Unreal Engine and I have some difficulties with “Line Trace By Channel”, I’m trying to interact with an actor on the map using an interaction interface, and it doesn’t work. The game I’m working on is 2d. I started this project in a “Blank project”, and if I try to recreate exactly the same thing in a “Third Person” project, it works in this “Third Person Project” I deleted everything and recreated the same 2d map with the same character, and to my surprise it works.I think it has to do with some predefined properties in the test projects and that’s why it works there.
