Hello, Since it’s a Microsoft/xbox game and uses those credentials make sure to clear not just the xbl from credential manager but Microsoft as well.
Also try clearing the Microsoft store’s credentials as well.
Press the Windows Logo Key + R to open the Run dialog box,
type wsreset.exe -i
and then select OK.
Since you’re on steam, steam might be saving your login, try running the game with cloud saves disabled, right click on the game in your steam library, go to properties, and find cloud save, you can either delete them or disable them temporarily.
Hope this helps,
JC
