Me too same issue, and the errors always mach the latest patch number. I have tried every fix online, Steam and the forums here to try and fix it. I have disabled my antivirus, made sure my graphics card was up to date, uninstalled, reinstalled, checked cache, tried adding different codes to ini that people suggested on steam and other ark forums even uninstalled steam and reinstalled it. after trying everything I can do i finally submitted a report to shooter games and all Shooter game support does is send me links to here or other information that does not pertain to my problem. So don't bother doing that it is just an other headache to add to the one you already have. SO I am guessing that they are baffled too. just keeping my fingers crossed that soon it will get sorted out. I really miss being able to play.
