"Loading and Compiling Shaders" every single time I run the game

Every single time I open the game it has to "load and compile shaders". This takes about 5 minutes and happens every single time I open the game. 

In season 9 it just gave me a black loading screen for 5 minutes every time I tried to connect, now it tells me it has to load and compile shaders. This is taking way too long to open, not worth it.
