Hey! I've done what you said and it still doesn't seem to work in a new project with a re-downloaded file. Would you be able to possibly do a tutorial video on this plugin eventually? No clue what's going on here, thanks!
The nw.js-version can cause the issue you described. Follow this step-by-step-guide to update the nw.js-version. This can fix the issue and it can be the reason why I can't reproduce the bug. I run my testgames with nw.js-version 0.104.1. Anyway, I recommend to use the latest nw.js-version.
