Client broken (as if its a f*cking suprise)

So.

When I go into queue for a normal draft everything works fine. However, as soon as the ready check pops up: BOOM, frozen until the ready check is over. The already plain stupid part is that ARAM works fine, but not draft.

I've tried restarting, reïnstalling, repair tool, nothing worked.

Riot. It's been 10 f*cking years. We had legacy launcher. That one was fine. Why did you have to screw it up.

(And just to be clear: I do not by any means have a crap pc or something. GTX 1050 and i7 processor.)
