Can't escape "Fetching Realm Information" screen.

[ Background ]
While creating a world, I accidentally pressed on "Create world on realms" from the world creation menu. The Minecraft got stuck on that screen, I couldn't press anything or exit the screen by pressing the "esc" key. This happens consistently even after reinstalling Minecraft.

• 1) Play preview
• 2) Create new
• 3) Create new world
• 4) Create on realm server

[ Expected result ]
I can escape / exit "Fetching realm information" screen.

[ Observed result ]
I CAN'T escape / exit "Fetching realm information" screen.
