I think this issue relates to this one: moveit/moveit2#1474
Moving the MGI initialization before the SingleThreadedExecutor should solve it.

  moveit::planning_interface::MoveGroupInterface move_group_interface(node, "panda_arm");

  rclcpp::executors::SingleThreadedExecutor executor;
  executor.add_node(node);
  auto spinner = std::thread([&executor]() { executor.spin(); });
