Getting kicked by anticheat 30 seconds after joining every game ("EAC Authentication timed out")

This happens every time I join a game. I would get kicked, and a message would pop up saying "Kicked by EAC: Authentication Timed Out (1/2)"

Before the update, I had to validate my steam files and the game worked after that. After the update, I get kicked even after validating files.

I also get this. I haven't played a single game yet because before I'm finished setting up my load-out, I get kicked for EAC Authentication timed out. I've seen recommendations for restarting the game or Steam, but none of those have worked for me.
