Hi there, I am having an issue where UE4 viersion 4.24.3 is crashing every time I open my map which features a pointcloud (.pts).

This issue first started after I decided to restart my pc when my fps was getting low in the editor. Upon trying to re-open the map, it would crash immediately. The scene consisted of the pointcloud, some spot and point lights, a skysphere, and exponential height fog.

This is the error code I received,

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0xffffffff
