EA APP via Gamepass ultimate on PC windows 10

I've been having a lot of trouble getting the game to function. I have the game installed on steam and am able to install it fine there, I've only managed to get it to actually launch a handful of times... and I do mean a handful; 4 or 5 times at most. I get the "an error on our end prevented your game from launching" error as well. I've tried just about every solution that I've come across that's been suggested and nothing has been able to resolve the issue. I even tried installing the game on a secondary PC with different hardware as to rule out my system being the issue; same issue there. Of the 4 or 5 times I managed to get the game to run I'm probably approaching upwards of 100 instances of "Your game failed to launch due to an error on our end." I'm able to launch every other EA game in both my EA library and Steam library that has to ping the EA app without issue... Sims 3 and 4, Star Wars Battlefront 2, Titanfall 2, heck even the original Mass Effect games.

As one last hail marry attempt I tried installing the game on a secondary EA account purely through the EA app (no steam connection whatsoever) to see if perhaps it was an issue with either my steam and/or origin account... but then I ran into the same exact problem you're describing. Attempt to start the download and it hitches at 14% for a few minutes before finally giving up and giving me an error prompt; something to the effect of "There was a problem with your download, please try again in a few minutes" - however I'm able to go over to the Apex Legends page literally seconds after and start a download of that with no issue at all. 

I really want to play this game; a game I've paid for twice now in an attempt to find a solution- but I'm at a complete loss at this point. It just feels as if a higher power has decreed I shall not play this game; or at least not unless it just randomly decides to work as in those handful of instances where it felt up to it for some arbitrary reason. 

Edit: Didn't realize until after the fact I was signed in as the secondary EA account I mentioned in my above post... disregard my random jumbled letters of a name.
