[CLIENT] League won't open when I have fixed it

The first time it happened I double clicked it but it wouldn't open so I opened as administrator and fixed it, I played a few games and closed it. When I opened it again it just showed the league Icon and disappeared, in task manager when I double click it, it will appear but then disappear from task manager. I have to open it as administrator every time I open league and have a 1-minute fix. It has become a habit but it is still very annoying when it won't open through double clicking.
