Version / build of AC (19 as in your profile? But your version of El Capitan is out of date there...), - all windows/doors? all wall types? etc.? The screenshot shows such a big error, something else must be going on or you'd see 100's of posts about the issue.
Save a module of the wall with the door in it, zip it, and post here for someone to look at... and/or contact tech support.
