I am having the same problem. I have tried deleting the website folder as talked about in Getting started with HTML5, but it didn’t work, and I have no idea how to let it find the .bin folder.
I use a Windows 10 PC and ran the game on Firefox and Chrome, to the same result. My Corona simulator is version 2018.6.25. Is that a more recent version? I don’t know…
I get the error when playing index.html on Firefox and Chrome.
