If you haven't already, try deleting the config.json file in documents/my games/terraria
I had the same issue and deleting that file fixed it

you are gonna need to post some details about your setup, config and stuff for there to be any chance to find the cause for this

Things to try if you have not already:

- Are you running Steam as Admin (rt click on steam shortcut, pick run as admin)?
- Are any AV programs (even WinDef) blocking access to My Documents?

I've run into both in the past (not just for Terraria, for any game that uses My Documents > My Games for saves and config files) when running Steam.

Valve has an entire help article on this (Steam Support :: Games do not run after 'Preparing to Launch')... but would like to rule out any Terraria-specific issues in case there is some aspect of this solveable on our end.
