[CLIENT] Afk for couple hours on the new client, come back and can't play

When I left the PC afk for 2 hours, came back to the screen i was on (soloQ que up with bot and mid selected). I pressed search or whatever for a game and it made the noise and changed icon and everything. Just couldn't join, couldn't press quit either, same effect. I could go to home and profile and stuff though.

Not sure if crash or client so.
