Rust Crashes when I try to load a server.

Hey all. Yes. I can get into the client seemingly fine- though the second I try to go join my friends on a server my game crashes. before I re-installed it it seemed like it kicked me before I even got to the server menu, but at least now it waits for me to actually join.

Is the the infamous “Facepunch error” I’ve been hearing about?

If so - how do I get rid of it?

Any help is appreciated, thanks!

Note - I do Alt-tab out of the game fairly often, if that may affect it somehow. =/
