I am not from Laminar Research; just a flight simmer from down under.
Unfortunately there is no good news.
Version 11.40 is still in beta format. Unless you are an experienced x-plane user and dabble in beta testing you should stay away from beta versions.
You need to have a look at the following link found at https://forums.x-plane.org/index.php?/forums/topic/160879-thinking-of-downloading-a-x-plane-beta-version/
Having looked at that link then have a look at the following two links by Austin Meyer (creator of X-Plane) found at https://www.youtube.com/watch?v=v4UfGE-JJY4 and also https://www.youtube.com/watch?v=WROEk_Jv33w
Austin is "running" the problems with this beta version. You should make direct contact with him setting out your specific problem(s). His contact details are given several times in the two videos referenced.
