Hey @Emilian-Vior
Your Steam account needs to be linked to an EA account in order to play Apex, this means that if you have previously played on Steam that it was already linked to an EA account.
You most likely linked your Steam account to a different EA account, meaning that it's now accessing the progress from another EA Account that doesn't have any progress.
It's possible that you might get your progress back if you were to link your Steam account back to the EA account it was originally linked to.
Though you're probably unable to do that, since it's possible that you won't be able to unlink it for 6 months or longer due to security reasons.
You can try contacting EA Support to see if they'll be able to do anything for you, but it's quite unlikely.
