I've found the issue with the second monitor AC plugin. It is not importing dependencies correctly (this is what you get for copy pasting code ). I should have a fix ready in a day (I'm quite busy now with IRL stuff, sry), which will fix that. It will work if another plugin is using (and correctly importing the same dependecies). I.e. CrewChief, so installing crewchief and enabling its plugin (you don't need to run the app), should, in the mean time, make Second Monitor work.
