Can you please let us know what console you are playing the game on? Do you have a digital or disc based version of the game? If you have a disc version, have you checked the disc for any scratches or smudges? Have you tried uninstalling and reinstalling the game and updates?
Can you please post your dxdiag or pc specs for our reference? Have you verified your game cache to make sure none of your files have become corrupted? If not, you can do so by following the steps here Verify Game Cache Files. I also recommend trying the suggestions listed here via Activision Support.
