Is there any way to get playerController of Client that ran RPC server function?

Hi, I have a problem with getting player controller of Client in RPC server function.

I know how to get all client player Controller but

when one client runs RPC function of server side, I can’t get a playerController of the client that just ran RPC function on server side in the function.

any way to solve it?

Thanks for answer.
but it keeps crashing when client tries to get an instigator controller and get player state in RPC Server function.
