Riot can u at least tell us when u will fix the client that wont let us connect to game since WEEKS?

There are currently three sorts of clients bugs/connection issues i experienced.

1: "A critical error has occurred" after loading screen / "Game is still running" but you cant connect / Sometimes no Play-Button. 2: "Cant connect to the servers" combined with a black loading screen 3: Avast Internet Security kicks you out of game after a couple of minutes (deactivating Avast helps)

Sometimes it helped to manually close the processes via Task Manager or restarting PC sometimes NOTHING helps.

How long do you want to ignore these bugs?
