Welcome Arminas Breivė,

I understand how frustrating it can be when launching Microsoft Flight Simulator 2024 purchased through Steam, you are prompted to sign in but receive an "Account Mismatch" error. 

Before proceeding, could you please clarify:  

  • Are you signing in with the same Microsoft account that is currently signed into the Xbox app on Windows? 
  • Have you previously used a different Microsoft account with Microsoft Flight Simulator or Xbox services on this PC? 

In the meantime, you can try these steps below to troubleshoot the issue:  

Option 1: Verify the Microsoft account currently used by Xbox services  

  • Open the Xbox app 
  • Select your profile picture 
  • Confirm which Microsoft account is signed in 
  • Try launching the game while signed in to that same account 

Option 2: Sign out and back into Xbox services  

  • Open the Xbox app 
  • Sign out of the account 
  • Restart the PC 
  • Sign in again with the intended Microsoft account 

Option 3: Check the Microsoft Store account  

  • Open Microsoft Store 
  • Select your profile icon 
  • Verify the account matches the one used in the Xbox app 

Option 4: Clear Xbox identity information  

  • Open Settings > Apps > Installed apps 
  • Locate Xbox and Xbox Identity Provider 
  • Select Advanced options 
  • Choose Repair, then Reset if necessary 

Option 5: Update gaming components  

  • Open Microsoft Store 
  • Go to Library 
  • Install all available updates for Gaming Services, Xbox, and Microsoft Store 

I hope the steps above help you deal with your issue.
