Client Going Black

Since yesterday there have been multiple times when I queue for Ranked Solo/Duo and when the queue pops, I hit accept, however when I'm taken to Champion Select the entire client is black. I can no see or do anything, even when it's my turn to pick, and it forces me to dodge from me 'not selecting a champion in time." Whether it be from banning or picking. Really infuriating, and I'm lucky it hasn't happened during a series.... But it's still incredibly aggravating to then not be able to queue due to a 'dodge' that wasn't my fault.
