League of Legends Won't Load After Champion Select for a Week

For the past 6-7 days, League of Legends refuses to load after champion select, even after restarting my computer multiple times. Sometimes it works, but often it doesn’t. I’m not the only one with this issue – two of my friends are also experiencing the same problem. Does anyone know how to fix this? Should I try uninstalling and reinstalling the game? I’m getting really frustrated and don’t know what else to do. If anyone has a solution or advice, please let me know! Riot Games needs to resolve this issue quickly as it’s affecting gameplay for several players.
