Missing UWP AppModel API forwarders break xgameruntime.dll (Forza Horizon 6)

[TheEX1T]

Forza Horizon 6 exits silently with no Xbox login popup.

Diagnosed via WINEDEBUG=+loaddll,+module — xgameruntime.dll loads
but immediately shuts down all threads because these API forwarders
have no implementation:

api-ms-win-appmodel-runtime-l1-1-3.dll → GetCurrentPackagePath2
api-ms-win-appmodel-runtime-l1-1-0.dll → PackageFamilyNameFromFullName
api-ms-win

fh6-loaddll.log

-appmodel-runtime-l1-1-0.dll → PackageNameAndPublisherIdFromFamilyName
api-ms-win-core-registry-l1-1-2.dll → RegQueryMultipleValuesW

Without these, Xbox Game Runtime has no auth context, login popup
never appears, game exits.

System: CachyOS, wine-cachyos 11.0, RTX 3070, kernel 7.0.5
