[CRASH] A critical error has occurred and the process must be terminated ...

Whenever I get into game at around 20-30min mark, my game randomly crashes. I know it says in the description: "3rd party software installed on your machine", but I know for a fact that I don't have anything open besides discord. I uninstalled/reinstalled the game multiple times, did what a youtube tutorial told me to do, used the repair function on the client and i'm still getting this error whenever i'm in game. I really don't know why this is happening. Started happening after the recent patch. It seems like its a random occurrence because some days I would crash every other game and other days i would crash every game. It always seems like its around the 20-30min mark. But please, I just want to know how to fix this. Thank you.
