Unity Player keeps crashing

I’ve been trying out rust since today, but the problem is that my Unity Player keeps crashing.
When I join the server, it runs fine for 30 seconds, and then my whole screen goes black with a error saying that my unity player had crashed. I also use firefox if that matters.
Any help please?

Just and idea its could be that you are using to much of your CPU, try closing a few programs down in the back ground that you are not using

it says my CPU usage is only 20%…
