HELP! Please UE5.3/.4 DOF issue low res edges

Hi everyone i having very serious problem with DOF. I am trying all different settings in movie render with anti aliasing but i can’t get clean and smooth edge in every part where the DOF affect the mesh . I don t know why is some parts the dof works and the other parts there are jagged edge. Can someone help me please? Can perhaps be the motion blur the problem? the character is moving

It’s look like it’s happening on areas that might have a fuzz shader affected, as it’s on the ears and also the tangent of the collar. Do you have fuzz shaders in use?
