I've tried all the methods described by support and more I've seen on Youtube, reddit, and the like, just this morning I got what really worked for me, I'm a windows 7 user, what did I do for resolve gone!
1 - Install update "KB3140245" restarted the PC
2 - Install "MicrosoftEasyFix51044" and restart your PC again!
Then the launcher returned to work normally, it gave an error several times in the update, I just closed it, and reopened it when it happened, until it downloaded the necessary and I was able to enter the game normally... I hope this helps somehow the people with this same problem...
