After update Minecraft Launcher does nothing.

A few days ago i opened up Minecraft Launcher and it started an update, later when it was finished i launched Minecraft Launcher but to no avail, i checked Task Manager and Minecraft Launcher was technically running but it wasn't using any CPU Power and it wasn't doing anything with my disk. It's been a few days and it's still doing the same thing. Whilst writing this bug report i opened Minecraft Launcher again for a screenshot and it updated but is still doing the same thing.

There is a screenshot and a video of the problem attached.
