Have you checked for double vertices or edges?

[chatofking]

I just checked there is no double edges

what should I do??

Delete and rebuild is one thing you can do.

[chatofking]

this is already rebuild one.

I mean just that one edge. Delete and remake the face either side.

BTW - there are vertical edges visible on the front edge of the seats that also need the freestyle removed.
It looks like you need to turn off the highlight curves option in the freestyle settings. All those lines above the red circle, and the dense areas on the corners of the white objects look like they do not need freestyle on them.
