4.25.1 Lidar import crashing

Hi, So Im trying to import lidar files. Namely one. I have a rather large LAS file and it gets 5% into it and crashes.
Im assuming this is due to my pc only containing 16gb of ram.
I read it can read very large files and this one is upwards of 230gb.

Im sure this is limited by my Hardware but there is nearly no literature on the feature I can find for this version.
I will likely need to vastly decrease the size. But is there anything I can do?
I also cant find any literature or video describing how I can either use this terrain as my game terrain or bake a heightmap from it.
