Fix your fucking game

A couple days ago, I gray screened on game load in (cursor is there, whole screen is gray, can't quit or switch applications). The only way for me to get out of this is to shut down my computer and restart it. Since then, I have repatched twice with the hex tech repair tool, reinstalled twice with the hex tech repair tool, and deleted the game from my computer and actually redownloaded it from the play lol site. Yet, I am still getting gray screened on my load in.

Side note: I am on a 2017 MacBook Pro

If anyone knows how to fix this, please let me know.
