The account is still unable to play normally after the ban is lifted

MA01fdXwLv3  Outside of referring you to the EA TOS Team, there's unfortunately not much else I could suggest, (especially when I don't work for EA or for Respawn), as when it comes to bans, that's the EA TOS Team's department.

However, from the sound of things, your EA Account "isn't banned", but your access to the game itself could still be banned, (so you
could try asking the EA TOS Team if there's any bans or suspensions still in place on your account in any way).

As for this question:

I didn't see any information about my account being banned in my ban history.

Some bans may not appear on your ban history page, (to which I'm not sure why some don't show up).

Regarding the login error, something you could try to do, is to sign out of the EA App, (or out of Steam), and then sign back in, (and it might also help to clear the EA App's, (or Steam's) cache), however, I'm not sure if doing so would resolve the issue.

To clear the cache on the EA App:

• Head to the 3 lines in the top left of the EA App, and then click on it
• Hover over "help", and then select "App Recovery"
• Click on the "Clear Cache" button
  
  

To clear the cache on Steam:

• Click on "Steam" in the top left corner
• Click on "Settings"
• Click on "Downloads"
• Lastly, scroll down and click on "Clear Download Cache"

Note: If you're using Epic Games, its a lot different, as its download cache is located in "%localappdata%/EpicGamesLauncher/Saved" (without the quotes), in the folder "webcache", (you would just delete the "webcache" folder), but make sure that the Epic Games launcher is fully closed out of before deleting the "webcache" folder.
