When I press 'Esc' and try to click on one of the options my game crashed, I can guess It's because there's nothing to be executed when pressed, and I would like to suggest you some ideas with what you can make it execute.
1. The option 'Load' can open the UI of the server browser.
2. 'Restart' restarts the server (very important because of the bugs/glitches).
And the other bug is that in other langues wicth aren't english pressing 'T' wouldn't trigger that chat script.
