Apex hangs forever on the loading screen after the intro

somewhat similar thing was happening to me. I had to do a clean boot, then do win + R, msconfig. Hide all microsoft services. Then add half of your services back in. restart. launch apex. 

If it breaks, you know a service in the first half is breaking it, disable them all then start adding them back one at a time (it takes forever but its worth it). I eventually found the service (ASUS lighting service) breaking my game and disabled it. 

Been working flawlessly ever since. Worth a shot.
