I know this is old but this is constantly happening to me too: UE5.3.2

I can’t work on my point cloud for longer than 5min before this happens

Same here. cant seem to find a solution.
It was working for me in UE5.2, but it could only handle a small file and crashed when I try to import 2nd point cloud

Sorry for not responding but it looked like to me it was a VRAM issue for those that are wondering. It is likely that the graphics card hits it upper limit of VRAM and just crashing trying to load in all the points. Try and optimize as much as you can as it seems it likes 12GB+ of VRAM on a card
