1.16 Pre Release not loading

This might be just me but when 20w21a started (also when Mojang Studios was introduced) Minecraft cannot finish loading to the main menu. What I mean is that when you enter the game, it will keep me on the loading screen forever. The bar only goes up to like 9/10 of the way and it freezes and doesn't take me to the game. When I go to any previous versions, Minecraft works fine. What is going on?
