My construct doesn't work even though I've quit the dev mode.
Clean cache doesn't help either.
I don't see a dev addon in the addon manager view.
How do we deal with such situation?
Develop games in your browser. Powerful, performant & highly capable.
It looks like it's trying to load a developer mode addon that is not available because your local web server stopped responding. Clearing the browser data should remove the addon install.
