This only applies if you have discord open.
For some reason the Discord overlay was crashing my rush when trying to join the new server, it took me forever to find this out.
Just go to Discord User Settings > Game Activity > Uncheck the little overlay monitor icon to the right of rust to turn off the overlay.
Or just disable the overlay entirely if you don't want it.
Then my Rust was able to connect, hopefully this helps someone!
