Mincraft Launcher wont open.

Hello.

Today I was playing on a Minecraft launcher called "Lunar Client". After I was done playing on that client I switched over to the regular Minecraft launcher. When I double clicked it nothing popped up, there would usually be a window popping up saying play no or switch version. In this case the launcher wasn't even opening. I tried everything I could think of, I tried reinstalling, running trouble shoot but none of that worked. I found It odd because Mincraft launcher would always pop up whenever I opened it. I never experienced a problem like this ever. So I am writing this to get information on what I can do to fix this problem.

-With thanks.
