I got the following on the HTML version:
"Unable to parse Build/Inky b0.3 web.framework.js.br! This can happen if build compression was enabled but web server hosting the content was misconfigured to not serve the file with HTTP Response Header "Content-Encoding: br" present. Check browser Console and Devtools Network tab to debug."
Btw, please designate the operating system compatibility of your executable. I had to download it to figure it out.
