Having issues starting the game
Application folder: C:/Users/xxxxx/Desktop/raty racer There should be 'RattyTheRacer WIP_Data' folder next to the executable
I got the same error as well, but I managed to open the game by renaming the "Sandbox_Data" folder:
As "RattyTheRacer WIP_Data"
To close the game, you have to open Task Manager and close it from there, since it doesn't have an exit button.
