Why does this game hate me?

So I alt+tabbed out of a game after champ select and before SR loaded. Now any time I try to re-enter the client it minimizes. Doesn't matter whether loading screen or on the rift. I've tried restarting the app multiple times, doesn't do anything. What did I do to deserve this? This is the second game in a row I'm going to get a leaver on for no fault of my own. WTF.
