Mission Completion: Unable To Select A Reward

Despite having a 2 year old account, I’m rather new to playing the game. As such, I’ve still got the login rewards to collect.

Problem: After completing one of them, I was given the reward of unlocking one of three champions, Brand, Morgana, or Ziggs. Unfortunately I am unable to select which one to unlock and can no longer play the game because of it. When I hover over any over the characters’ names with my mouse the options to see their abilities or select that champion come up. However, when I go to either see their abilities or select that champion, those options disappear, leaving me unable to exit the selection screen.

What I’ve done: I have tired closing the League App and opening it again. Upon reopening the app it immediately went back to the selection screen and left me with no changes to the problem.

I have tried restarting my computer and then reopening League, but again, it immediately went to the selection screen with no improvement to my problem.

If anyone could help it would be immensely appreciated.
