[2022] Frame drops after a few incursions, that trigger at 2nd sub-zone.

After I've played a few incursions, there is a frame drop that happens as soon as the 2nd sub-zone starts, and been happening all the time recently, I've checked and my PC isn't giving any throttling or high temperatures as they stay in an average range of 68-73 degrees celsius. I didn't have this problem before when I purchased the game early this year, and these problems have only happened recently.

Be greatly appreciated to know what's going on and if it's a bug in-game or if I have to do a deep check of my PC (as other games are working fine and having no problems).

Thank you.
