Forza Horizon 4 PC won't launch, or says sign-in needed

So today I excitedly opened up my pre-ordered Forza Horizon 4 and seems that the splash screen shows up for 4 seconds, disappears and the game won't launch.

I've searched on Internet and found out you need to download a random app from the Microsoft Store app and the game launches.

It wasn't the end. When the beautiful music started, the awesome graphics showed up, I immediately pressed Y on my Xbox One controller. The game still won't let me play. It's a $60 game and I shouldn't be treated like this. Luckily I found another fix on the internet, it turns out that you need to do the following steps to get everything working.

  1. Press Windows key + X

  2. Then click Windows Powershell (Admin)

  3. Now type the following commands and hit Enter key

    Get-AppxPackage *windowsstore* | Remove-AppxPackage
    Get-AppxPackage *xboxapp* | Remove-AppxPackage
    Get-AppxPackage -AllUsers| Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}
  4. Open Xbox app, and you should be able to sign in and play. Enjoy!

It's also possible that RTSS which comes with MSI Afterburner software interferes with FH4, close the app if that's the case. MacType can also prevent the game from launching – just add ForzaHorizon4.exe under [UnloadDll] section in your MacType ini file, and restart your computer afterwards.
