[2021] I'm stuck here. No matter what I click in locked out of Path of Champions. I've tried relaunching and even logging out of my Riot account. No dice.

Hi! I've got a few troubleshooting questions:

1. Based on that dialog, this step should be asking you to click on Jinx's face. It's obviously not glowing, though it should be. Can you confirm that pressing on her does not open the UI?
2. Can you upload your client log somewhere so we can take a look?

Hi! We're investigating this and working on a permanent solution. In the meantime, if you open a player support ticket they can fix your account.
