""Rust"" (EAC Disconnected) & (Rust.exe has stopped working).

When i go to launch Rust from (Steam) As soon a i click play then (Play Rust) it always comes up with Rust.exe has stopped working, i have re-installed the game several times, even re-installed Steam and then installed Rust again but comes up with the same problem and there is no way around it, if their are any solution for this please help.

When i try to go into a server I always get the problem (EAC Disconnected) and can never join a server (I can only join Battle Royale servers) besides those I cannot join any other server, is their any solutions to this aswell?

Thank you for taking my problems into consideration.
