Can't sign in to MSFS through microsoft

Press Win Key, type Microsoft flight, Click App settings and do repair and or reset.

If that doesnt help,

uninstall steam edition and manually remove all remaining folders, probably in steamapps~

& uninstall and reinstall MSFS and also remove remaining folders in C:\Users\YourUsername\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe after uninstallation and before reinstallation.

Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community.

Hello LewisBeese, sometimes this may be some windows update that remains to be done, on Tuesday Microsoft released important updates to the operating system, be it Win 10 or 11, ideally it would have it with the latest version installed.

See which version of Windows 10 you have

Updates often seen as optional, Microsoft released major fixes this week, and make sure you have the Xbox Companion App installed.

If you haven't updated yet, click the link below, update and then make all subsequent security updates.

If you want to change the accounts that can log in to Apps and programs on Windows, you can go to: Settings»Accounts» Emails and accounts, and add or remove the account you want, and then reinstall Steam and log in with the Microsoft account you want to see if it takes over in-game.

Hello, MSFS will be tied to your Microsoft account so you should not need a code as long as you use the same Microsoft account to reinstall MSFS

Hopefully google translate hasn't messed this up to much !!

Hallo, MSFS wird an Ihr Microsoft-Konto gebunden, sodass Sie keinen Code benötigen sollten, solange Sie dasselbe Microsoft-Konto zum Neuinstallieren von MSFS verwenden

Go to task manager -> Details. Find GamingServices.exe and GamingServicesNET.exe and end the tasks. Then launch MSFS ON THE Microsoft Store, not through the start menu. It worked for me, hopefully it
helps you too!

Ok. That allowed MSFS to start. Now MSFS is giving me a message that a required update is needed and to update from the Microsoft store. But I've run the updates from the store and it says everything is up to date and MSFS doesn't give me an option to trigger a manual update.

So now what?
