Fortnite Bug,?

Hello people / experts, for a long time I have a problem with my game. And while I just stand still, my character automatically moves to the right, even though I can't press any keys on my keyboard, but it can't be because I've already tried another key to move to the right, and that made no difference, Fortnite is the only game where I experience this bug.

I would like to test follgendes test in the game keyboard and if the movement is still is nen bug in the game with you
