High CPU Usage And Crashes After Recent Hotfix

Recent two days, I have been getting unstability in game.

I rarely have any crashes for the entire season 9, and the first week of season 10 went well too.

When the latest hotfix dropped yesterday, I have been having lots of crashes.

Today alone, I had 24 crashes.

The crash behaves like this:

1. Game video feed either freezes at the frame, or blacks out with unresponsive Apex window

2. Game's sound keeps playing the same moment, then drops

3. Usually at this point it goes back to my desktop, or I just end task out of impatience

I do not know how to troubleshoot the issue, because:

1. The crash usually doesn't leave a trace inside of Windows event viewer

2. I am using Steam version of Apex Legends, not sure whether I would have any crash log text files

3. I do have .dmp dump files, which I have no way to interpret

4. I cannot upload .dmp or .zip files here

I am using 3080Ti + 10700KF, it has been great for all of the games that I play, and Apex Legends itself, up until yesterday.

I was OC'ing CPU's core clock to 5.1GHz (rather average OC result), today I have to manually slow down the core to 4.9GHz for the game to run without much crashing.

GPU OC doesn't seems relevant.

Besides, usually when I f up my GPU OC, it crashes with a dialog stating some DirectX error

Anyways, I did try using WinDbg to analyze the dump file, here's the output:

This dump file has an exception of interest stored in it.
The stored exception information can be accessed via .ecxr.
(297c.1060): Access violation - code c0000005 (first/second chance not available)
