User Interface Vanished

All facets of the User Interface outside of the Marketplace and Dressing Room are invisible. The settings menu is completely invisible, making it impossible to adjust anything in the game. The create/load worlds menu is completely empty, but can still technically make a new world. When accessing a world, only the toolbar is visible and the movement controls are fully invisible. The UI selectors at the top of the screen for pause, emotes, and chat have also disappeared. I forgot to mention: created characters are completely invisible except for sharp edges of the model when moving the character in the menu screen.
