I get the above error message after trying to start Stardew Valley. I had tried to mod with SMAPI, and apparently broke something. This message is after uninstalling SMAPI, the two mods, and the game, reinstalling (Game only) and then following a "how to fix your game" thread on steam forums. at this step of the steam thread: Delete Stardew Valley startup_preferences. Go to: %AppData%\Roaming\StardewValley Delete startup_preferences. Start Stardew Valley. My computer says %AppData%\Roaming\StardewValley isn't in there... So I can't progress on that "fix" New information. I think it may be a steam issue (although they disagree) because when I navigate to the stardew valley folder and click on the application file itself (the .exe?) it starts!
