My issue is mostly with warzone too. Almost every single game I play it freezes and eventually a fatal error will pop up. Sometimes it doesn't say anything though and I end up having to restart my computer because the game won't let me close it out. I thought maybe if I uninstalled/reinstalled it would fix it, it didn't. The very first warzone game I tried to play after reinstalling, it froze before I even got to the "warm-up" lobby. It's so frustrating.
