With the latest bugfix (1.16.220), Minecraft on Switch has become absolutely unplayable. Just starting the game causes the entire system to freeze, forcing a manual restart. I found that after I reset the system once I'm able to at least get into the game. But then whenever I'm in a world, the game will just freeze for about 5 seconds or so for no reason. This is just the latest of reasons why Minecraft on Switch is the worst version of Minecraft.
