Halo MCC disappeared after I paused the update?

If you interrupt an update or cancel it, without using the pause feature, that update is corrupted, and corrupt the entire game.. Before shutting down your consul or computer, pause your downloads to make sure that they can be resumed successfully

Sorry for the inconvenience mate
I hope you can download the game again as soon as possible!

Dang yeah it’s gone. Tried that not there, showed up in my download queue, guess I’m gonna have to wait for the rollover date on my wifi lol. Thanks trying to help though.

Thanks for clarifying that.

Buddy, we can try performing a power cycle reset to see if the game finally appears:

1. Turn off your console by pressing the Xbox button on the front of the console for about 10 seconds, until it shuts down completely.
2. Unplug the console's power cable from the console and from the power outlet. Wait 5 minutes.
Important: Be sure to wait at least 5 minutes. This step resets the power supply.
3. Plug the console power cable back in.
4. Press the Xbox button on your console to turn it on.

After that, try looking for the game in your downloaded games.

If finally MCC doesn’t appear unfortunately you may need to download it again

Yeah I wasn’t able to find anything on my games list, when I went to my entire library it showed up but prompted me to go to the store to download it. Did it actually just delete itself off my Xbox? I can’t afford to redownload it…

My apologies for not being clear before this is on Xbox Series X. I was a bit shocked so I forgot to say that exactly.
