Xbox series X will not install or update any games

Not really...

Xbox Series X games / upgrades / updates has to be installed onto the Series X internal or expansion card SSD,

You can have Xbox One games on your external hard drive that will get an Series X upgrade but the games will need to be transferred to the Series X and then the Series X upgrade will need to be downloaded onto the Series X SSD,

As an example...

I have Marvel Avengers on my external hard drive that will get the Series X upgrade and I will transfer the game over to the Series X SSD ready to download and update the game to the Series X version when available.

Update. The game will not load on my series X with any dlc installed. Only the base game.

It will load with dlc installed on the new profile. But I don't have access to the dlc since that profile doesn't own the dlc.

It will load on the Xbox one with dlc.

Hi,

Both Series X/S games and Xbox One games that been optimised (I'm British) for Series X/S must be installed on either the internal storage or the expansion card. They can not be run from a USB connected storage device. My optimised Series X/S Xbox One games
were moved to my Expansion card during their update.

I don't know if these server problems are related to the updates they do for the game.

I remember not long after I installed the game on my Xbox series x last year it received an update a day or 2 later and I started getting a server error message on my Xbox series x yet on my Xbox one x the game played fine without an error message.
