Stuck on loading screen

When I start Rust with steam I get the standard menu where you can choose controls and resolution,
then I click on “Play!”. After that it starts the game, but it doesn’t go further than the loading screen.
My screen doesn’t freeze, I can see my FPS(Fraps) changing from 1000-1200FPS.

My screen resolution: 1920x1080, Graphics quality: Fastest

Is there anyone here that knows how to fix this? Because I really want to play the game with my friend…
I can provide my PC specs, I just don’t know if it’s needed.

After using the “Verify intergrity of game cache…” function in steam it seems to be fixed.
Can an admin pls delete this post? Thanks
