Have to reinstall the game again on Steam

Thursday I preinstalled BF6. I havent been able to play until now because of work and now, I accessed the menus, went to play and found out I didn't have anything installed??? I have to download 50GB AGAIN when I already had everything installed but the game is saying I don't have it? Is it a crazy day 1 patch or wth? I am going crazy, just came back home after a 12h shift and I won't be able to play until tomorrow because of this, come on man.

Anyone knows anything about it?
