Call of Duty: Cold War/Blizzard Launcher

I’ve been having an issue in which I can’t join my friends’ parties in zombies, it says I don’t have the content installed, (when I actually do), so I’d have to join either in the main menu or in the multiplayer lobby. My game crashed last night, prompting for a scan and repair, which I have tried multiple times now, and a pop-up says “something broke, try again”. I keep trying every time it tells me that.
