Character jittering while turning or moving backwards

I’ve been using the third person template controller for unreal engine, and I replaced the spring arm component and regular camera component because they didn’t act as I wanted them to do. When i replaced these with new components, my character began jittering while turning around or moving backwards. I have tried expanding colliders, which didn’t fix anything, and I turned off the animator, which also didn’t change anything.
