Having an issue with the game deleting itself

I have the windows store version and it just randomly deletes itself. It has happened to me 4 times now. Its not a huge deal but it is annoying. Anything I can do to prevent PSO2 from deleting itself?

Seeing as it is an issue with the way the MS Store itself works, then your options to completely avoid the deletion issue are to use the Tweaker since it allows you to install the MS Store version of the game in a different place, thus circumventing many of the problems (though it does require you to put your PC into developer mode to be able to alter permissions) or to use the Steam version (though you need to have the MS Store version installed at the same time for a bit to be able to link your accounts and retain your progress on the Steam version). If neither of those options appeals to you, then there is really nothing that can be done.
