Call of Duty: Modern Warfare (2019) Will not start, HELP!

Game will not start, just reinstalled, and when I start it, it says “error has occurred while launching the game. Please check for updates or scan and repair to fix this issue.” and at the bottom it says, "More help: BLZBNTBNA00000012 (19). I already reinstalled, repaired and scanned, as well as checked for updates. What in the heck is going on? Never had this problem until I reinstalled it to play it again recently. I don’t spend my hard earned money on games I can’t play when I want, that’s ridiculous. I5 9600K, GTX 1060 6GB, 16 GB RAM, EVGA 650w PSU

Hi,

This forum is for community based troubleshooting of technical issues involving Legacy Blizzard games such as Diablo II: 2000 or games in the Blizzard Arcade.

Blizzard support for CoD games is limited to installation and patches… once the game is completely installed, you need to contact Activision for help; see Having Problems with Call of Duty? Read this first! for more info on this.
