Client just crashes in champ select

First of all sorry for not having this shown in a better way. Plays.tv was the only way i could think of. So if you watched the clip, everything just crashes. It started happening like yesterday or even today. It caused me to dodge a match a couple of times and i'm so sick of it. I have no clue why did it just start doing that. I have enough space on my pc and didn't download anything that would make it happen. Literally randomly started out of nowhere. would appreciate any suggestions you guys have. (btw don't mind my pick xd)
