Does this happen to anyone else?

I have been having this problem for 1 month. When I am aiming with any weapon and I decide to run, the sight suffers a downward deflection. This problem is exhausting because I always lose sight of the enemy. If you can see the video, this happens intermittently: the first time I do the aim and run action, it doesn't deflect. But then it does deflect and so on. Has anyone found a solution to this?

I have a RTX3060 with everything updated. Logitech Mouse and Keyboard and everything hooked up fine.
