I have noticed this with more than a couple of PC's now. The store icon is invisible in the launcher. There is a space there and when you click it, it opens the Microsoft Store but no icon. I have not been able to remove it nor edit it.
Might I ask which "launcher" you speak of?
Are you talking about ObjectDock, by chance?
Maybe tell us, 8 or 10?
Windows 10 / ObjectDock
