@Scilin this wont fix the problem as the files are on still on your computer and likely Microsoft has backup files of multiple versions of your game filling up your drive. The files are hidden in a folder called mutablebackup and copies keep getting made every time the launcher fails. You will have to manually clean these files to free up your drive space as Microsoft is useless and this in itself can be a chore if your not familiar. The first step is to turn on your ribbon on your file explorer, then turn on hidden files. From there you can go to your drive and select programfiles ->windowapps(the file is different color because it was hidden). Way down toward the bottom is a file called mutablebackup. To do anything with this file you must take ownership of it and its contents through the properties and advanced security options(google how to take ownership of files if you need help with this). This is where all the files micrsoft has moved are being hidden. I haven't personally figured out how to restore them but I also haven't bothered really trying. I wont be playing anymore though till this is fixed because its not just a "launching the game in admin" issue as being reported. Anytime the launcher has an issue this is subject to occur. It also seems the file backups are of random size being anywhere from 17 gigs to 68+ gigs per file set. At anyrate, until Microsoft and Sega figure this out or start paying me to continuously fix their errors I'm done.
