Crash on opening level

Development World Creation

Dealing with a crashing issue when opening a level. Any troubleshooting steps appreciated! Unreal 5.6. Level contains lots of Nanite foliage, landscape, PCG data.
Hardware Raytracing, SM6 enabled.

I think may have something to do with Hardware raytracing and need to run the following on launch
r.Lumen.HardwareRayTracing 0

Assertion failed: CachedRayTracingInstance.GeometryRHI == nullptr [File:D:\build\++UE5\Sync\Engine\Source\Runtime\Renderer\Private\PrimitiveSceneInfo.cpp]

I don’t know what the reason is, but you can add r.Lumen.HardwareRayTracing = 0 under [/Script/Engine.RendererSettings] in the DefaultEngine.ini settings.

This will set r.Lumen.HardwareRayTracing 0 on launch.
