I've manually reinstalled Emby Server 4.8 & repaired .Net - same crash. When trying to open Emby on a device I only get part of the home page (the Home/Favourites top line and then just a spinning wait animation in the center) before the crash happens on the server. From the server console if I select 'Configure Emby' from the tray icon I will get the whole of the config web page then it crashes, and no links from the webUI will work. EmbyServer.txt
