Whenever I attempt to open League of Legends, the logo would pop up, but then it will close itself out. Is there a fix to this?
What worked for me was that I went into Riot Games --> Elo boost --> League of Legends --> RADS --> Projects and deleted all folders except for lol_air_client and lol_air_client_config_xxxx (depends on what server you are on). After I deleted them I started the game again and I saw the logo loading. I had to wait for like 20-30 sec until the game started up fully patched and I could log in. I hope this works for you too.
