I cant launch apex legends after last update, i tried everything, but no

You're not alone.

I've had to re-download and repair the game numerous times now since the last update and still nothing.

Anti cheat loads but the game window constantly crashes after.  I've only ever played via the EA app but now I'm at the point of installing Apex on Steam.

I don't even know if I'll retain my account at this point.  But I guess we'll see.
