Howdy. I've putting off making this thread for a while. The game's been crashing for at least a week or two by this point, and I've been trying to fix it myself on and off but couldn't do it often due to internet issues. Now I have more stable internet, and I still can't, so I'm finally bringing it here.
Ok so basically, the update screen works fine. The login screen works fine. After that, the game loads up and then instantly closes out about a second after it loads. The process is still running in the background, but there's no way to retrieve it. It does this every single time. I've deleted the lol_air_client folder a few times to re-update, no dice. The PBE also has the same exact problem.
Exploring the lol_air_client folder, I found logs. The crash produces no other form of logs other than the logs that are found in lol_air_client/releases/0.0.0.229/deploy/logs. The logs have this to say:
