This prevents the game from running. remove the line and (without BUILD) the exe runs.
Example of a game.projectc file with the error
[resource]
http_cache = 0
max_resources = 3300
uri =
[input]
repeat_delay = 0.5
repeat_interval = 0.2
gamepads = /builtins/input/default.gamepadsc
game_binding = /input/game.input_bindingc
use_accelerometer = 1
gamepads = /builtins/input/default.gamepadsc
