LIDAR Pointcloud Turntable Animation Unwanted 'Motion Blur'

Hi everyone, absolute newbie here.

I’m trying to do a 360 turntable animation of a .las LIDAR pointcloud file. I set the pointcloud to rotate with basic key frames.

While in the preview the points look fine and relatively crisp when rotating (img 1), the images exported after I ran the render have some kind of long exposure or motion blur effect to it that’s not intended (img 2).

Would be hugely appreciated if anyone has some advice as to how to fix this!
