RealityKit scene with the Entity Component System

I'm following WWDC for interactive 3D content in reality composer pro and apple's document https://developer.apple.com/wwdc24/10102 https://developer.apple.com/documentation/realitykit/implementing-systems-for-entities-in-a-scene#Retrieve-entities-with-an-entity-query

However, this simple code to declare a dummy Component and System has compile error

/Users/Workspaces/repository/Packages/RealityKitContent/Sources/RealityKitContent/RobotComponent.swift:18:24 Static property 'query' is not concurrency-safe because non-'Sendable' type 'EntityQuery' may have shared mutable state

    // Define a query to return all entities with a MyComponent.
    private static let query = EntityQuery(where: .has(MyComponent.self))


    // Initializer is required. Use an empty implementation if there's no setup needed.
    required init(scene: Scene) { }


    // Iterate through all entities containing a MyComponent.
    func update(context: SceneUpdateContext) {
        for entity in context.entities(
            matching: Self.query,
            updatingSystemWhen: .rendering
        ) {
            // Make per-update changes to each entity here.
        }
    }
}

I'm using XCode beta3 and project target visionos 2
