Cannot join my own worlds nor make new ones

So within the last week I just got the new update towards the skins/wardrobe area where they completely redesigned, rearranged the entire closet. Ever since this silly update, now I cannot join my already made worlds, nor can I make new ones or even other peoples worlds. All I can do is servers. Please please please stop making these silly upgrades to everything, cause it’s to the point where I cannot even play Minecraft anymore without glitching or bugs interrupting.
