Game Crashing Over and Over

After starting a game my client will bugsplat, causing me to be unable to join in. Of course this is annoying for me, as I cannot play, but also wastes the time of others that are in game. Thankfully, each game that I have been disconnected in has been remade, but this still affects my lp. It has now happened 3 times in 6 games (I have deleted and re-installed multiple times), and I am not "eligible for seasonal rewards" now.

Does anyone know a fix for this? I am not interesting in re-downloading this for a fourth time.
