@Velkerath So after spending a few hours trying to figure out how to actually get this game to work. (gave up trying to do this because didnt care enough) I found this here from another forum
Those are the pathways for 3 folders that has the game, one of them can be accessed by you(First one), but the two others are locked by window store's premissions, but that can be changed back to you by using right click on them then properties. You can then change the owner under security tab and advanced, you add your name in the writing box and find name, yours will pop up, you select it then you apply the changes. Once that is done, you can now delete those files. The reason of this is because window store made everything unmodificable, so they are the one that will do update to the game which is the case for most games in window store and such hence why all permissions are usually under "TrustedInstaller", although, Saga made the game with a personal launcher and patcher, hence the patcher see himself in 3 different folders, he will add every file to every folder he sees. In short, that is a poor concept from both Microsoft and Saga. In short, the fix for Saga that they would do is that their dedicated updater would only apply all changes to one folder, the first one in the list above while microsoft moves their main pathway to that first one while deleting the two others off the user's computer.

Hopefully this will help you "uninstall" this game. Dont forget to check MUTABLE BACKUP This fucking folder was ANOTHER WHOLE GAME AGAIN So in total for me this game had about 250GB of space.
Oh also you might need to give yourself Permission for every folder. To actually delete them.
Here are the links to everything I found to help me deal with this problem.
Check pages 5 and 6 i believe it was for all the details for getting permission and other things
Pretty sure this is what someone right above us posted to help delete this game.
This might help in a way.
