FYI I found the solution which I put in another post but will provide here.
The solution was not to buy windows, it was actually to use the /fstack command in game and then mouse over the user interface elements to discover that there was a code issue caused by the Objective tracker overlaying another uI element.
This loading screen stuck and world server down seems to happen when a player moves UI elements around and saves the layout using edit mode (not addons). Then if the player changes the screen resolution it can result in the UI elements overlapping and this causes the loading screen errors.
So the game should be changed so that its not possible for a user to have there custom layout UI break when changing screen resolution size …but ALSO it should be made clear that these custom edit mode layouts do not seem to be tied to the WTF Cache or Interface folders, and they appear to get downloaded again from the server even after deleting these game folders. This seems to be the real issue as Face to Desk happens when u have reinstalled the game, formatted ur computer, removed all addons and the loading screen problem persists despite also deleting ur WTF cache and interface folders. TO recap this is an issue that happens because the new fangled Edit Mode can break your UI when changing screen resolutions and graphics settings that result in overlapped ui elements.
