[CLIENT] Launcher doesn't work

So my client has been doing this for over a month already but i didn't seek help. I can open the launcher and it will pop up but as soon as i press launch to go into the login screen the button comes back and the launcher just stays. I have been going on the player support page and trying every single solution for it but it still does not work. I have tried uninstalling and reinstalling it a couple of times now and i have tried to repair the client but after it repairs nothing happens and it stays the same. I would very much appreciate if someone could help me in fixing my issue. Thank you.
