Do I need a new xbox because of this problem?

Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community.

Hello, what exactly would be the game you try to play and not getting?

What console model do you have, an Xbox One, or any of the new generation, Series S/X?

Your console is connected by Wi-Fi or network cable, is this happening only with this game or with all console games?

If you can give more details, I'll be waiting for your reply.

I've factory reset the Xbox twice and still kicks me out of every game I try, tho I've noticed that before it kicks me the power button on the Xbox blinks 3 times. Is that a faulty sign or something? It's never done this.

Hello again, is your Xbox One X plugged directly into the socket, or is it plugged into some kind of electrical stabilizer?

Does it have any peripherals connected as a keyboard, or even an external disk?

Hello again, we have received many reports of bugs and errors regarding MW2, we recommend some procedures in the console, but I believe they will only improve when Activision release some update with fixes for these bugs.

However I see that you are struggling with other games, if possible put your console connected to the network cable, and try to do a reset while keeping games and Apps.

Xbox One reset keeping Games:

Press the Xbox button to open the panel.

Select system > Settings > System > Console Information

Select Reset console.

Restore and maintain my games and apps.

Rest assured, you won't miss games or saves

Note: You need to know the email and passwords of your accounts when performing this reset.

I have a xbox one X and the games are all of them but I get different error messages for example for modern warfare 2 the new one I get a dev error, minecraft it says it's corrupted n to reinstall, n for fortnite it says to restart. Im on wireless internet connection
