Minimal robust placement flow.swift

    @MainActor
    func placeInRealityView(modelURL: URL, into content: RealityViewContent, under parent: Entity?) async throws {
        let entity = try await ModelEntity(contentsOf: modelURL)
        var mc = ManipulationComponent()
        ManipulationComponent.configureEntity(entity, collisionShapes: nil)
        entity.components.set(mc)

        let anchor = AnchorEntity(world: .zero)
        content.add(anchor)
        anchor.addChild(entity)

        Task { @MainActor in
            await Task.yield()
            if let parent {
                let hadMC = entity.components.has(ManipulationComponent.self)
                if hadMC { entity.components.remove(ManipulationComponent.self) }

                parent.addChild(entity, preservingWorldTransform: true)

                if hadMC {
                    ManipulationComponent.configureEntity(entity, collisionShapes: nil)
                    entity.components.set(mc)
                }
            }
        }
    }

@durul thanks, but the ManipulationComponent has no member isEnable, did you extend the ManipulationComponent?

There you get the Scene, if I look by make Realityview I can get the scene.

I've updated it. Sorry for sharing the wrong snippet; you probably couldn't compile it. I don't know your code or project, so it's hard to estimate your needs. Good Luck...
