[Client] reconnect bug, disconnecting after pick phase

The pick phase finished and then the client would minimize and then reappear. It would stay as a black screen for a bit and then the reconnect button would appear. Every time I pressed the button the above process would happen. So far I have restarted the client, restarted my PC and used the Hextech repair tool. I tried again later in the day and the same issue happened and then game me a leaver warning after my team remade for the second time :/
