No Main Menu Rust Experimental

Since 2-3 days, I cannot launch Rust Experimental because whatever I do, the main menu doesn’t display.

I reinstalled the game 2 times, but there is no differences. Here’s a copy/paste of my output.

Is there a solution or it is a bug? I can’t see recent posts about this problem so I assume I am the only one. But I’ve got no solution.

Happened to me a couple of times last night randomly. Once I restarted and it fixed itself, another time the menu appeared on its own after a minute.
