I think this will gona be help, Just rename and add some text in the end in your fgo data. Example "com.aniplex.fategrandorder.en" become "com.aniplex.fategrandorder.enzz". After you rename that data delete the old fgo and instaled the new one, beffore you open the fgo, make the data name back to the first again "com.aniplex.fategrandorder.en"
