Modeling crashes my UEFN

Summary

Hi I thought I’d post here to see if anyone can help me figure out what’s causing this.

I have been working on a Mini-BR map in UEFN, the size of maybe half of a typical Dev island. With this map I have had to do a ton of modeling and I’m fairly new to the toolset. Something that consistently happens though is modeling anything whether that be making a corner smooth between 2 objects or creating 45 degree ramps for roofs or ramp connectors, or even cutting a whole through an object to connect it to other areas smoothly crashes my UEFN/UE5 with no warning. This has made me lose a lot of progress and is hampering my speed of designing the remainder of my gray-box. I’d love any help here as most of the videos I’ve seen only reference crashing on the start of projects.
