Battlefield games stopped working, but I can still play EA Sports FC on my xbox?

I played battlefield 6 the past two days, but as of today I can't anymore all of a sudden. I get "an undefined error occurred". Error code 1:86001S:89001S:9C:-13561655840.

If I go to my EA account, I see there aren't any linked platforms, but my XBOX is connected to EA. When I try to link it to xbox from the EA account settings it says:

Your accounts can’t be linked because your Xbox account *********** already linked to your EA Account for 4b*****@anonymous.ea.com. An EA Account can only be linked to one Xbox account in its lifetime. 

(FYI: I removed my account name in the error message)

The anonymous email address is obviously not the email address from my xbox account.

I have also tried resetting my xbox, rebooted my modem and router, tried different networks (wired and wireless), reset the cache, removed the reserved space, tried other dns ip's, tried it on my fathers xbox (he has the home xbox to share games). Nothing has changed in the xbox settings or network setup.

I also failed trying to connect to bf1 (it won't go online) and bf5 (you are not eligible to participate..)

I am kinda clueless to why I suddenly can't play anymore. How do I fix this issue?
