Game not loading past splash screen unless I restart pc after every match

So everything was fine, I went on vacation for a week, come back, see there's a massive update. Updated the game, tried to launch, game would just not load after the splash screen. I restarted the PC, game loaded up, played one game, and when it was loading to a new map the game crashes and I again cannot load past the splash screen. Restart, game loads, tries opening a map, crash, can't get past the splash screen again. Each time the game does crash I try to check with steam, and it tells me it can't update or do anything because of a "Disk Write Error". I check the folder, I can access, change, do whatever I want on the disk fine. I run an integrity check on the drive in case, drive is 100% fine. I'm thinking it has something to do with the anti cheat, so I uninstalled and reinstalled it, but having the same cycle as above. I see a lot of people having issues starting this game after the latest patch, hoping there's some news on how to fix it.
