changing settings crash on steam?

i was playing and changed my anti aliasing from 0x to 8x and the game froze then crashed and now every time i open it it crashes

Start in windowed mode.

yeah… I can’t play anything but windowed mode safely and I’ve dabbled.

When in windowed mode press alt-enter to make it fullscreen without crashing.

same for me also im playing on the lowest setting and still have crazy lag issues and it crashed and now it doesn’t bring up any servers for me so i can play at all ?
