Sorry for the late reply. This error has popped up more frequently recently because an update to PennController in the Empty Project unexpectedly affected existing projects. Your project appears to no longer have the PennController.js file in its Modules folder. Just download the file from PennController’s github repository and then upload it to your project’s Modules folder
