I am opening the game from the xbox application,
the game and the anti-cheat does not open, only that error appears accompanied by "timeout

I have the same problem!! I have bought this game and click the MCC, it launches, I see the "easy anti-cheat" window load, then the opening cinematic plays, it then closes or crashes when the "343 industries" shows
and the Halo Reach Microsoft app page is opened and says I need to install Halo Reach. But I did install it!!!!!

That's where a separate anti cheat file is for me. Though I have my gears files there as well (but I can't open the anti cheat file listed within the gears program.)

I have the same problem with MCC anti cheat coming up and not letting me play. I have a new lap top running windows 11. I also had this problem on another new laptop running windows 10, I am not able to play any of the multiplayer games in the Mcc. I am able to play the single player maps but when it comes to multiplayer I cannot play.

I was able to play at one time on windows 10 with my old laptop but i did not have steam downloaded or running on my laptop. This one and my last laptop had steam downloaded with games open but they were closed at the time of downloading and trying to play the game.

There are two options when you start the Mcc in multiplayer one to play the second to play with anti cheat running, i have tried both and they do not let me the anti cheat keeps coming up I am wondering if anyone else also has two options to pick from? Is Mcc the only halo game that this comes up on, or does it also come up on all the halo games?

If I was to delete steam would the problem, go away?

In both cases i have deleted the Mcc and have not reinstall it back to my laptop. With my new laptop I was surprised to see the error again.

I also have the Xbox pass running windows 11 the laptop is only 3 weeks old

I would appreciate any help someone can give me to help solve this problem without deleting steam and the games I have on it.

Thank You
