Guys, i really highly doubt that there is any need to do these things.
As one can read in other posts, this is often caused by broken cloud storage files. You dont have to install anything at all.
In the rare cse you can fix this by relogging in store + xbox app, you dont have to install anything.
This doesnt work always so one has to manually sign out inside the sim as well.
Then to make sure sign out and in in store as well as xbox app, restart pc and it should be back, including all your settings etc.
