100% CPU usage/ frequently crash down

Before the Event update between 9.16 & 9.17, my PC's CPU always stay below 35% while running the game.

After the event update, my PC CPU goes to 100%, and the game crashes randomly.

I've followed every method this link provided:

https://answers.ea.com/t5/Technical-Issues/100-CPU-usage-troubleshooting-steps/td-p/10707752

Changed every graphic effect setting to the lowest.

Adaptive Resolution FPS Target is 60.

I also use +fps_max 60  command.

But it doesn't help at all.

The crashes behavior is a little difference after the updates on 9.22.

Before 9.22, the crashes usually follow with a screen stuck first. 

When I tried to use the glide move, or Gibraltar opens his dome. My screen got stuck and then the game crashed

After 9.22, My game still got stuck for a while, but after that the game can still continue without problem.

But the crashes become randomly. The game just crashed without any sign.

Is there a crash dump file or game log I can provide to help you solve the problem?

My game ID is HOYO if it helps.

I think many people really like this game. So the more problems we met, the more frustrating we get.

Hope you guys can find an ultimate solution.
