Sometimes when you create a windows build inside the folder is the file “game.projectc”
There is a line showing an empty declaration of uri =
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
