Resolved Why when using a freelook camera on my player the camera is shaking/stuttering ?

I will add some screenshots and a shot video gameplay when it happens.
The problem is with the cinemachine camera because i tested also in another new clean project and also tested it with just a simple Camera.

With a simple Camera it was working fine smooth but with the freelook camera it's shaking/stuttering in both projects.

First screenshots of my player inspector components settings :



The next settings screenshot is of the freelook camera :
kid_from_space is my player with the settings in the top first screenshot.




Solved !

A working solution at least for my case was to change in the Main Camera in the cinemachineBrain component the property Update Method to Fixed Update and this seems solved the problem.
