Have you tried deleting the map from your map folder and reloading? Some map developers change map features without changing the version of the map so tf2 tries to load the old version as its already downloaded.
The error says that the map is missing. If there was a map present in the map folder, the error would be different if the map was outdated.Have you tried deleting the map from your map folder and reloading?
