Horizontal blur line

Hey! I just want to ask for help. I’ve been rendering this animation by png for how many times now. It’s been days already actually lmao. When rendering the animation, there’s this big blur horizontal thing in my pngs. The rest of the frames are okay but when the radial blur effect is already starting, the blurry horizontal thing will appear. Note that it doesnt appear when played in the preview window.

How can I solve this problem without having to change any of the effects?

Could you provide a .sif or .sifz file that shows this problem?
