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.
