Objects blur when camera is moving

Hello everyone,
Like the title says, when the camera is moving, all other images are blurry except the player sprite because the camera moves with it. You can see when my
player stops moving, ie the camera also stops moving. The treant that’s chasing the player becomes much more visible. How do I fix this?
Player movement is done in fixedupdate so my camera movement is also done in fixedupdate. I’ve tried update and Lateupdate, neither seems to work.
I know there’s another similiar topic out there but I have checked that post and it does not help me. I am not using cinebrain camera. I don’t have HDRP neither.

EDIT: I guess the quality of the video is a bit hard to tell so I updated a second video.
while moving, if the camera is following the player. Everything else gets blurry.
If the camera is not following the player, only the player looks blurry. I have tried
the interpolate on both ridgedbody and it’s not helping.
Second video:

IDK why but I have fixed it. I tried cinemachinebrain’s camera and no combination worked.
The only solution is to execute my follow camera script in lateupdate. interpolate both the player and treant chasing him. Don’t know why it works but it does :confused:
I’ll just take the W and leave it
