hi i need help whit this error

Hi, I’m a long-time Apex player on PS4. I recently bought a PC and I’m trying to download the game to play from here, but I keep getting this error. I’ve tried everything to install it, and I think the issue might be the anti-cheat not opening at all, but I’m not sure. If anyone has had this problem and knows the solution, I’d really appreciate it. Thanks!
