Got through steam and can't play

I am getting the Error 'Rust Launcher Error: Loading Error - StarService failed (577) Any help would be appericiated

In my case Rust does never starts from the first time. When I start Rust for the first time, the process is actually running, even my steamavatar is showing up a green border (in-game status), then I always need to kill the rust process. When I start the game again for the second time, it launches the game properly, weird… someone else has this issue too?
