I have been silently browsing this thread for a few days and I have the same problem and what Oulabird said may have something to do with it. Maybe it has to do something with workshop addons or something? Maybe with the default profile, once you download something off the workshop it changes something that, after a recent update, was changed in the update and now is screwing something up? I don't know, just trying to put some thoughts in to try and help this get fixed quicker.
