Servers deleting the Main Menu

Pretty recently I joined a random TTT server in the server list. As soon as I get in, my game crashes to the desktop, so I shrug it off. When I got back in the game, the entire main menu other than the background is gone, but I can still use the console. I know that the menu can be deleted, I’ve helped someone test it before, but this seems like a sort of big issue, should it be dealt with?

E: Can I get the main menu file(s) back, by the way?
