Xbox series X shuts down after launching any game

Your answer is not satisfactory since the issue is specifically with Xbox Series X and S so far as I've seen, which are systems that came out well after Mixer shut down. I have been streaming on Twitch through my Series X and even I cannot stream a single game now, every game states "this game does not allow streaming" including games I HAVE streamed in the past.

So there's something else going on that is not "we shut Mixer down over a year before this console launched"

Hi,

Yes I did this the other day and it still shuts down after I quit the game, I have checked all my settings and nothing is set for the series x to shut down when I quit a game.

Since the Xbox Series X is said to be able to play Xbox games from all previous generations (i.e. the original Xbox, Xbox 360 and Xbox One), they probably won't shut down the servers for Xbox One in the foreseeable future.

It would not make sense to put work into making Xbox One games run on the new Series X (which is a major selling point, as Backwards Compatibility was the No.1 requested feature after Xbox One was launched without it), and then discontinue Xbox One support.

So rest assured: You can continue to play your games on your Xbox One, even after the Series X is released.

However, game publishers might still discontinue support for older games and the server infrastructure. EA is well known for shutting down the servers for their older games for example.

And with Minecraft being very popular among families and children, which often use the "handed down" older consoles, they wouldn't want to lose the market by making it impossible for kids to play older versions of Minecraft by shutting down servers.

By the way: unless you play on Realms (i.e. Bedrock), there are no servers to shut down. All worlds are hosted on your own device, and use the standard Matchmaking for multiplayer. So you can continue to play your Legacy Console Minecraft until your console
dies and you can't get spare Xbox One consoles anymore.

The only reason I don’t think Xbox 360 servers will be shut down anytime soon, even after series X comes out, is that you still have games that I’ve just been added to backwards compatibility and those games will continue on when series X comes out. A
lot of the backwards compatible games have multiplayer elements that need servers so it wouldn’t be a good idea to shut down games you just released.

Maybe Xbox Live is shutting down on the 360 to make way for the series x/series as s?
