Samsung J3 2017 here. I solved this problem of having the repeat small window appear stating: “Google Play Store Has Stopped” Close App.
I went into Setting -- Apps. From here I opted to have the Apps Listed. I selected Google Play Store and clicked on, Force Stop. I was given the option to reset Google Play Store to basic, beginnings, function ability. This I did. From here the annoying repeat window (above) disappeared. I then updated all my apps. Regards.
