Your client is failing to load me into games Riot

Mysteriously, just today, even though nothing is wrong with my computer and I had no issues for weeks prior to this morning, your garbage client is failing to load me into game. I'm now up to 6 attempts to load into a match, each has failed, either sticking inexplicably at 100%, or black screening and making me unable to alt tab out or use task manager the second the loading screen comes up.

Elderwood Hecarim is the skin being used, I never select skins, but today I have for each of these games and this is literally the only thing done differently than previous games which worked fine as recently as last evening.
