I made a post on reddit and has my code snippets (https://www.reddit.com/r/cpp_questions/comments/c9kgw8/how_do_i_use_this_state_machine_from_sonar_systems/)

I’m getting my error code when I try to use the statemachine. I created a StateRef and StateMachine member to my engine class then tried passing in the StateRef through the State Machine’s AddState Function and got the error code C2280: and mentions something about a function being deleted. I will not that the tutorial series offers no instruction of how to use the statemachine, only how to make it. a tad frustrating.
