Cannot link/sign in a Microsoft account with my Steam copy — error 0x89245104 / 0029

Hello,

I am unable to sign in to a Microsoft account in my Steam copy of Minecraft Dungeons II (Steam appid 1912410). On every launch the game immediately shows:

• Cannot sign you in to Xbox Live

• Sorry, something went wrong. Please try again later. (0x89245104)

0x89245104 corresponds to the GDK error E_GAMEUSER_USER_NOT_FOUND ("User matching the ID was not found").

I have ruled out the following through controlled tests:

1. It is not a Microsoft account problem.

   • All of my Microsoft accounts ([email protected], [email protected]) fail;

   • A friend's Microsoft account — which works perfectly on his own machine — also fails when used with my copy of the game.

2. It is not a PC problem.

   • Logging my Steam account into another, known-good PC and running the same game also fails;

   • The same friend, using his own Steam account and his own copy, works perfectly on that same PC.

3. It is not a network, proxy or region problem.

   • No VPN and no system proxy during testing;

   • The account has no enforcement actions (enforcement page: 0/8, no active suspensions);

   • Xbox privacy & safety settings allow multiplayer, cross-network play, clubs, etc.;

   • Players in mainland China can sign in to this game normally without any accelerator.

4. All standard fixes have been tried and none worked:

   • wsreset.exe (Microsoft Store cache reset)

   • Microsoft Store: Xbox app / Xbox Game Bar / Gaming Services confirmed up to date (Xbox app 2609.1001.16.0; Game Bar 7.326.8061.0; Gaming Services 38.117.18001.0)

   • Gaming Services Repair Tool (completed successfully)

   • The game's bundled GamingRepair.exe scenarioExternal (Engine\Extras\ThirdPartyNotUE\GamingRepair\exe) — Microsoft GameInput was reconfigured successfully

   • Deleted / renamed the game data folder %LOCALAPPDATA%\Dungeons2\Saved

   • Signed out and back in on both the Xbox app and Microsoft Store

   • Re-linked the Steam account inside the Xbox app

   • Changed the Microsoft account region (China → Japan) and the Windows region

   • Added the -windowed launch option

   • Rebooted the game and the PC multiple times

   • Used the in-game "Sign in with your Microsoft account" entry

My conclusion:

The problem points to the server-side "SteamID ↔ Microsoft account" binding record for my Steam account. On every launch the game reads that record and tries to sign in the account stored in it; if the record is broken or points to a no-longer-valid target, the game reports 0x89245104 ("user not found"). This also explains why signing in with any other Microsoft account locally makes no difference — the game does not use the locally signed-in account, but the one in the server-side binding.

My request:

Please check and clear the server-side Microsoft-account binding for the Steam account below, so that I can perform a clean re-link afterwards.

• Steam display name: zChenXplorer

• SteamID64: 76561199178572815 (account ID: 1218307087)

• Game: Minecraft Dungeons II, Steam appid 1912410

I can provide error screenshots, the %LOCALAPPDATA%\Dungeons2\Saved\Logs logs, and a written reproduction of the controlled tests above.

Thank you very much.
