So while I hung out in the steam Chat I found out that it isn't normal to can't open his consol in the main menu, but that is my problem! The consol works fine while I'm in a map but on the main menu it isn't appearing if I use the key that's bound to it. It only shows up if I quit the server and get back at the main menu while it was open in the Server. I already tried to reset the keysettings, but this didn't help. As Long as I use the coonsol it always wasn't appearing on the main menu, so I don't think that any mods(that I don't use) destroyed it.
