@Tammors I’ve had this error before. What fixed it for me was to reboot my computer. If that doesn’t work, try logging out of the ea app, rebooting your computer, and then logging back in. Hope this helps. I logged in right after I updated, and everything seemed fine for me. Have you updated your game with the patch today?
Edit: I re-read your post, and the error you’re getting is a bit different than the one I’ve seen before. I’d still try it, it may work. Also if you use mods, you need to update them or remove them after a patch
