The most recent update, hotfix or patch completely broke my game on PC. 5624 and 5409279981 0xc0000005

So the past 2 weeks I've been busy with moving into a new apartment so I haven't been able to play modern warfare much because of this. I built my new PC in preparation for my new office and played around 6~ hours or so before the move went down.

Fast forward to yesterday and I finally get to sit down for an hour and on my first launch of the game I get "DEV ERROR 5624". I have never once gotten a Dev error code, even before the move to the apartment so I'm assuming it was an update from within the 2 week time frame.

I launch the game again and play a 2v2 gunfight tournament with my friend and we win it on our first try. That's around 25 minutes or so of gameplay? We que back up for another tournament and the first round of the first match my game freezes and I get this "Error Code: 5409279981 0xc0000005"

TLDR: Does anyone have a fix for

DEV ERROR 5624 (when I launch the game)

Error Code: 5409279981 0xc0000005 (my game freezes and this pops up)
