My World keeps freezing.

Hi. In the most recent update on the Nintendo Switch Minecraft seems to freeze constantly. I'm not using texture packs, yet it freezes whenever I try to build, mine, etc. Along with that I keep thinking told I'm in an invalid game when I try to access market place. Marketplace Will not load at all if I try selecting it on the main menu. With how it is I can't play the game for any extended period of time without getting frustrated.
