My issue was fixed two days ago after almost a month simply because of connections with a streamer friend being able to put me in direct communications with them. There is no way for you to fix this issue on your end if you're specifically getting the error code 1:86001S:51009S:11468332130:1073807360Q. The error code 100% factually has to do with your account having two EA IDs which should not be possible and the game is trying to authenticate using the other / old ID. Unless you have direct coms I have no idea how you'd fix this because your profile numerical ID has to be changed on their end to fix the problem and public EA support is outsourced and will not understand any of this. The person I spoke to confirmed that I was legitimately the first person to report this issue and diagnosed the problem over the past month because apparently the error code itself had no documentation at all.
The only thing that will work is if you're playing on Steam and you unlink your Steam account from your EA account, create a brand new EA account, and link your Steam to that new account. You're going to completely lose any account progress and have to start from fresh but if you bought the Phantom Edition you'll still have access to that content + the battle pass. If you bought the game on the EA app or on console, I don't have a solution for you.
That's not an ideal fix unfortunately as I have spent 60 hours + on it and collected all the tags in the campaign, Completed all the challenges etc. I don't think I'd have it in me to do it all over again. But I am using steam.
