How to solve CInemachine free look camera shaking/glitching,

So, i made a cinemachine camera and as i look around it seems to glitch a lot like shaking and other things, i saw it in the scene view, and it seems that it isn’t the character (the thing that the camera is following) that is shaking, it’s really the camera, i saw a simillar question and they said to change the update method in the cinemachine brain to the method the character is (FixedUpdate), but it only gets worse. Any ideas of what it could be? ,

btw idk if this is relevant but i got a texture bug where all the textures became pink, then i removed the URP and it fixed it
so i don’t have URP or HRDP or something like that idk
