New to UE5, and while trying to work on a project for learning purposes, the project randomly crashes. I am using Lumen Lighting, and Nanite meshes, including multiple desert nanite ground meshes for floor. Whenever I am working in UNLIT mode there are no crashes. However randomly when I can adding meshes or changing something in LIT mode the engine sometimes freezes for a sec, then crashes. I currently have 2 LevelStreamingVolumes for lighting but I get “multiply lighting” errors, (not sure if relevant but thought should add)
