I have reinstalled my windows so it's clean.
I have re-downloaded the game, repaired the game.
Used DDU to have clean nvidia driver installed.
Started as Admin.
Repaired EAC.
Everything is fine with windows firewall settings.
( Also done the full EAC removal form Zeel's post )
Every "Fix" video out there does nothing.
The game just refuses to open at all, and just goes back to origin with no message what so ever
Windows 10
32gb ram
1080 Ti ( no overclock )
i7-8700k ( no overclock )

Had this exact same thing this morning. I tried some stuff such as reinstalling and repairing EAC. But in the end I got the game working by NOT running the game and EAC as administrator.
To do this, find the game installation folder and right-click the Apex Legends executable 'r5apex'. Open 'properties', and then the click on the 'compatibility' tab. This is where the 'run this program as an administrator' option is. I got my Apex to run by deselecting this option.
Perhaps this might also help in getting your game to work, as well. Good luck!
