Cannot Leave Party

Whenever I log into League, I'm automatically put into a party of 1 and cannot queue for anything but Blind pick. I've tried logging out, restarting my computer, dodging a blind pick game, playing a blind pick game but it will not let me leave this party of 1 and I don't know what to do so I can continue playing.

I've seen many discussions regarding the same issue dating back to 2014 but I haven't seen any solutions. Open to suggestions.
