Hi @Fjedski,
Let's take a look and see if we can help with the errors you've been seeing.
First, have you had the chance to try repairing the game in the Origin client to see if that helps at all? If you right-click on Apex Legends in the Origin Library you'll see a Repair option when the menu comes up.
Let me know if you're still running into this same error message after that. Thanks!
