Huge lag spikes and freezes

Hi. I've been playing Apex Legends for a few months and everything going well until the recent 2 updates. My game keeps getting huge lag spikes and then it freezes sometime after the lag spikes. The weird part is that I don't see any significant FPS drop from the game performance info ( it does sometimes but mostly not ). it lags so hard that I can't even play the game. it feels like 30 Fps even though my fps is always from 110-120. There is no overheating on any part of my pc but I did find out whenever my lag spikes come in. My GPU would be dropped to around 20-40% usage and it only lag spikes mid-game. Both of my CPU GPU would be around 60-80% usage when it is running smoothly.

I've been trying every method from the internet like changing all kinds of in-game video settings / capping my max fps to my monitor refresh rate / changing Nvidia control panel setting / shut down window game mode / updating all CPU GPU drivers etc... nothing really seems to work.it really upset me. I really hope that someone can help me ☹️  Please let me know if there is any way to fix this.I am willing to try anything!

Anyways. Thank you so much for reviewing my question 🙂

Here is my pc spec :

CPU               : Intel Core i7 10700F 
Mother Board : Z490-A PRO
GPU               :  ROG STRIX GeForce RTX 3070
RAM               : 16 GB DDR4 2667Hz x2 (2 channel )
