I usually play the Minecraft Bedrock edition in multiplayer such as servers but I wanted to play singular mode by myself for a while. When I tried to create a new world (The settings were all on default mode), and after I pressed "Create World" the app just seemed to blink and showed "Creating world" for a split second before it returned me to the menu where I was trying to create the world. I also checked for updates, my account, and restarted the app and went back to creating a new world but none of them worked.
