This should be fixed in the newest version!

If you have this or any other issue in the future, feel free to open a new ticket!

i resolved it with the following:

				FMeshBatch MeshBatch;
				FRealtimeMeshBatchCreationParams Params
				{
					[](const TSharedRef<FRenderResource>&) {  },
					[MeshBatch = &MeshBatch]()-> FMeshBatch& { *MeshBatch = FMeshBatch(); return *MeshBatch; },	
					[&OutRayTracingInstances, LocalToWorld = GetLocalToWorld(), FeatureLevel = GetScene().GetFeatureLevel()](const FMeshBatch& Batch, float MinScreenSize, const FRayTracingGeometry* RayTracingGeometry)
					{
						if(RayTracingGeometry->Initializer.TotalPrimitiveCount > 0)
						{
						check(RayTracingGeometry->Initializer.TotalPrimitiveCount > 0);
						check(RayTracingGeometry->Initializer.IndexBuffer.IsValid());
						checkf(RayTracingGeometry->RayTracingGeometryRHI, TEXT("Ray tracing instance must have a valid geometry."));
						FRayTracingInstance RayTracingInstance;
						RayTracingInstance.Geometry = RayTracingGeometry;
						RayTracingInstance.InstanceTransforms.Add(LocalToWorld);
						
						RayTracingInstance.Materials.Add(Batch);

#if ENGINE_MAJOR_VERSION == 5 && ENGINE_MINOR_VERSION < 2
RayTracingInstance.BuildInstanceMaskAndFlags(FeatureLevel);
#endif
OutRayTracingInstances.Add(RayTracingInstance);
}
},
GetUniformBuffer(),
LODScreenSizes,
LODMask,
IsMovable(),
IsLocalToWorldDeterminantNegative(),

};

				if(OutRayTracingInstances.Num() > 0)
				{
					RealtimeMeshProxy->CreateMeshBatches(LODIndex, Params, Materials, nullptr, ERealtimeMeshSectionDrawType::Dynamic, true /* bForceDynamicPath */);

				}
