Rust: Process already running

Hey there,
when I try to start Rust, there’s always a small Steam-info-window that tells me, that Rust is already running (Although i just started the PC or closed Rust for sure).
I always have to kill the process and then start Rust again. I don’t ave Rust on Autostart or something like this.
Anyone got an idea or is experiencing the same?
It’s not a that hard bug, but still kinda annoying to me.

Thanks

Thanatos

Personally I find it happens when I try to launch to soon after opening steam. Give it ten seconds before you try. That works for me
