League of legends launcher is invisible

This problem is occurring in which my league of legends launcher is invisible. I open it, it shows the application is open, but I can't interact with it in any way. The same happened for another launcher called Epic Games for Fortnite. However the solution to that one was just finding the edge of the invisible launcher and resizing it by dragging it to the edge of the screen, however I cannot seem to use the same solution for my League of Legends launcher.
