[CRASH] Game crashed during a ranked game loading time. This is the third time.

This is the third time a bug-splat has forced a remake in a ranked game. I don't know if this is my computer or related to a client issue, please help me. The champ select is normal as always, but when I get to the loading screen my client crashes with a bug-splat and returns me to the home screen. What is strange about this bug is that at the top left for the league button, it scans for a corrupted file which takes a solid 10 mins for me. I told my duo to not remake if they could, but I understand if they had no choice or faith. Because of this bug I was placed in low priority queue for the second time... now it takes me 10 minutes to even enter the queue. Is there anyway I can fix this issue?
