Sprinting Bug?

Hi! I‘m playing on the Xbox and I’m sprinting forward when moving my left stick forward. I usually play COD and used to this mechanic. That usually works fine 90% of the time. But somehow I’m getting a bug where I‘m not able to sprint, I’m stuck in a slow movement until I let go of the left stick, stand still for a moment and then I’m able to sprint again. I don’t recognize a pattern when it happens, it seems kind of random. Does anybody also have this issue? Is it a bug are maybe intentional?
