I tried everything I found on the net to play Apex...

If I install it on my hard drive I get the infinite loading screen but Easy Anti-cheat seems to works perfectly (+ it works perfectly with Fortnite).

If I install it on my SSD drive I get the error :

This client is not running anti-cheat, or has failed the anti-cheat authentication : authentication timed out ( 1/2 )

Any help on this error please ?

I tried to repair Apex legend, starting it with different compatibilities, as administrator, reinstalling it + origin, fixing the DHCP etc. Nothing worked.
