Glitch Sound Apex Legend from PC

I am having a 'glitch' sound every single gunfight, sometimes in the middle of the fight and sometimes after the fight. The glitch sound is followed by an FPS drop which is really annoying.

it happen since the newest season update and I never experience it since season 1 playing this game.

the solution that i tried : 

1. updating all drivers on my PC

2. Turned off sticky keys and filter keys

3. contacting EA Live Supports and followed their intructions which is deleting cache and stuff

4. Reinstalling the game

5. re contacting the EA Live Supports and they suggested me to make a thread here, so here I am.

And here's the link of my unlisted 4 sec video for further understanding about my problem.

I hope anyone can help me with this since it really disturb the gameplay itself.
