Cannot load or make worlds/ join realms or other peoples worlds(AKA can't play the game at all)

When clicking create or load world, it gets a few bars and then the bar freezes, the background freezes, the tips keep loading but after some time, it says that I need to check my internet connection and that I couldn't join/make the world. It worked perfectly fine about a week and a half ago but now I cannot even play the game. (EDIT: ONLY affects my main account. If I attempt to play it on a guest account, it works fine, but when trying to play worlds on my main account, it won't let me.)

 

(EDIT: Resolved. It was my paid for skin that crashed that game... why mojang.)
