Rust.exe has stopped working.

I’ve just installed Rust from steam and when I try to run it from Steam I get “Rust.exe has stopped working.” Is their anyone else with this problem? Its really beginning to frustrate me now.

I’ve tried uninstalling and using -force-d3d11 as a launch option which works but the lag is just unbelievable and I’ve also verified the integrity of the files.
