I paused Minecraft to let the map load after I got my starter, and when I unpaused, it made me choose my starter again and then crashed. 

And I already decided the name of my world:
Aibīgan.
A combination of the words Aibī (Ivy in Japanese. Named after someone's Wyngro I looked at before I made the world. Idk who owns her tho. lol) and Dangan. (Bullet in Japanese) 
I chose to translate the words into Japanese 'cuz I'm trying to learn Japanese and also I like naming everything with Japanese words. (Also, Pokemon is made in Japan so yee)
