Hello,
I had to google what Joiplay is, and found this:
The line it crashed on is something not found in all RPG Maker games, it's rather an "uncommon Node.js function."
If you are able to open the file located in www/js/plugins named LAMB_Title.js, you could comment out that one function, to instead of
require("nw.gui").App.clearCache();
make it:
/*require("nw.gui").App.clearCache();*/
that error should be resolved, but I don't know if it will run into any other errors.
