I had the issue, that starting windows gamepass related games redirected me to GameService in the Windows Store, which was installed and updated.
Then I made the error, trying to reinstall MSFS2020. It won’t start the download anymore, like for every game in the store, that isn’t for free at all.
It results in Code: 0x80070424
Meanwhile at least I can play the other games again, which I didn’t deinstall. I am mad about the fact, that I think, using the sim would have been able, too. But as I mentioned, it won’t let me download it anymore.
Any suggestions? Used google allready and had a look into the topics about similar problems. That’s why I at least could start the other games again. But I haven’t found any thread about the download issues.
Did you try the integrated troubleshooter for Store apps?
This code is related to missing services.

yes, I did, I’ve even did that PowerShell reinstall. That worked so far, that I can play allready installed games again. But it still isn’t possible to install new ones. Except the Free2Play games. That’s curious.
I had a similar problem since last week and tried all the proposed approaches: using powershell, dism and wsreset. And I don’t know how often… After more digging into the problem, I found out that the problem was related to the Appx database StateRepository-Machine.srd. Even after uninstallation, the FS package was shown as an installed package, and thus the store refused to re-install it.
So, to remove the wrong entry in the db, I tried the following instruction:
Repair APPX can be removed or reinstalled · GitHub
But since 20H2, MS added additional triggers to the database, which have to be dropped and added again after removing the wrong package.
Now, the store installs MSFS again 
But be carefull and try it at your own risk! You are changing things on the lowest level and you can easily breake your Windows installation. So, a backup might be a very good advise. Hope that helps.
