Ashley I spent tons of time on this and could still never get it to connect. I finally got the web upload on steam to work by extracting the files and recompressing them directly inside the x64 folder. Otherwise, I assume it was having problems with the extra folder called x64 inside. Not an issue with steampipe gui, but does cause problems with web upload. Anyway once that was figured out, I used a virtual machine with linux and did the same thing, so that it wouldn't lose permissions as you said. However, still the same result. No CEF steam connection during gameplay. Achievements cannot be triggered. It simply does not work in practice, at least not for me. I would love to use the steamworks plugins, webview2 and cef, but it seems to be impossible. Hopefully no one makes a whole project in a non LTS version of construct and learns this the hard way.
