Viewport wont stop scrolling

I am looking for any help as it seems I cannot get my viewport to stop moving the camera to the side by itself. I have shut down and restarted the engine with the same effect. any help would be appreciated.

likely you have a controller plugged into your pc and it is giving a slight input on the sticks. if you do have a controller plugged in then remove it and possibly restart the engine.

if thats not the case let us know.
