Champion select crash

Since tickets take 3-4 weeks before getting a reply I'm posting here. Right as champion select ended, my game crashed on loading screen and did so about 5 times before I gave up and repaired. Now I am in 20 minute low priority que. I have Windows 10 and all drivers are updated. If this low priority isn't lifted i'm probably quitting because I don't have an extra 20 minutes to sit around and wait around for, 5 times.
