Input delay and prediction error

For the last week, I have been completely unable to play Apex because of this. At first I thought it may just be my WiFi. But no this is the worst thing I’ve seen in a while. Out of no where I have input delay and prediction error symbols during gameplay followed by major lag and delay. How can this issue be fixed? I’ve completely deleted the game and redownloaded it numerous times, updated my nvidia drivers, clean wiped my whole PC and redownloaded everything back and it’s still broke. What’s going on with this. The game is literally unplayable.
