League screen goes black after logging in.

So, I found this bug recently. Basically, I open up league all normal, it launches after pressing launch. I get to the log in screen and I log in as normal, but then it takes me to this black screen. The league border is there, but it's just black. I thought it was originally from it loading, but I left it open for about 8 hours (i slept while this happened.) and it still was black. So I tried restarting my computer + Relaunching league. Both didn't work. It's starting to become very frustrating and I dont know** what** to do or how to fix it.

And to think this happens right after I wanted to play the new champ.
