DirectX Game Crash

So since Patch 7.13 went live, every time I try to load into the game after champ select, the game doesn't load and I get the error message that an unknown DirectX error has occurred and League of Legends cannot start. I've tried updating my video driver, updating my OS, deleting the files in both the RADS projects folder and the config folder, as well as uninstalling and reinstalling the game.

I'm currently on DirectX 12 with an AMD Radeon 7700 GPU.
