Today I installed an update via Pacman and first no games would launch, so I tried restarting Steam. Much to my disappointment, Steam would not start. The output I'm getting in my terminal when I run steam is

Running Steam on arch rolling 64-bit
STEAM_RUNTIME is enabled automatically
Installing breakpad exception handler for appid(steam)/version(1433441724)
