Please Help - Critical Error

I am running the game on Ubuntu, the game was working fine about 3 weeks ago. After installing some prerequisites for Unity 3D my computer crashed and i needed to reinstall my desktop manually through the command line. Ever since then I have not been able to get the game to run. I FINALLY got the Client to open through trial and error. However, now that I have the Client opened, I cannot get the game to run as soon as it tries to go full screen. I have tried doing full re-installs of League, Wine, and Lutris as well as checking the game.cfg files and graphics settings but none of these have worked. I just want my favourite game back please.
