Black screen blind pick after /remake?

This just happened and I got LeaverBuster for it.

So I started a blind pick with my friend, picked Urgut, got first blood, but they did /remake. The post-game screen wasn't loading in so I skipped it, she invited me to a blind pick, she immediately left it as I joined then invited me to another one. I joined, we started, found a match, I clicked where the typing area would be to try to type my lane as it usually does a short black screen that still allows me to type and get my role quickly, but this time it just stayed black.

I don't know what caused it, but yeah.
