Stuck At Home At Champion Select

I don't know how to fix this, im scared i will get banned due to how recently it has been happening. i have already spent 20$ on this game cuz i just NEEDED THIS EPIC RENWRECKTON SKIN :D

So first, i go into any normal game match, doesn't matter which and i click accept like any normal match. Then, while everyone must be selecting champions, im stuck at the home screen! And i've tried everyting to get back to the champ select! So, i try to ignore it, and just go to join another game and this happens! (insert ugh.PNG picture here). So, then i try to go into, "invite my own friends" while the champion select sound is still playing, and this happens! (insert WTF.PNG picture here). Then, when i know i can't do anything and im filled with ( i can't get into a game sadly) despair, i wait the music out, AND THIS HAPPENS (just waited 15 minutes, (insert WHY.PNG here).

Any fix lately?
