I am having the exact same issue as well except it is with the Mass Effect Legendary Edition. Other games like Titanfall 2 launch perfectly fine but this one refuses to launch. I as well jumped through all the hoops over and over many times now to try and get it to work. Even contacted support about it. The response I got from them was completely unhelpful. The gist of what they told me was they have no idea what the issue is nor how to fix it. So they noted the "bug" and they will fix it whenever they feel like it, aka never. So don't bother asking them they clearly do not care at all. This issue has being on going for months now. Also they told me to go check the forums to see if anyone else has had this issue and if they figured it out so here I am, again.
From what I suspect, and this is PURELY a guess so don't take it too seriously. The game has failed to active correctly somewhere in their system and it throws the "An error on our end caused the launch to fail. Try again a little later." error message back as some sort of failed check message.
