How to make sure the sys_error goes away on modern warfare 2

I have the Xbox one s it’s only this game that this problem is happening the worker said that to go to your setting and restart your console and keep my games and apps and it still doesn’t work which is insane

Did you tried reinstalling the game?

If not, please do it. And if maybe you have external USB accessories like a hard drive, please disconnect everything before and after reinstalling the game

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today despite this Reefie

Additional information is needed, please tell me:

What console do you have?
Is this happening only with this game or if you try a different game something similar happens?
And, what this Microsoft worker told you to try in your console?
In that way I can advise you different things or how to proceed

Depending how Modern Warfare goes, im sure they will look into it. TBH i loved the black ops campaign

Considering how terrible it was in Modern Warfare 2, no, not really. You can't hit something standing still from 5 feet away with that pistol.
