I pressed Spacebar in a recent game to go back to my champ and the screen was permanently stuck on Ahri. Pressing Y did nothing.
Pressing Y after pressing Y also did nothing.
I exited the game to try joining again to see if it would fix it, but instead, the game crashes every time and I'm prompted with
"The game has crashed.
Please try to reconnect to the game."
Exiting the client completely also does not work.
