World was working. Saved and logged out. Upon logging back in the game loads fine. You can jump, look around, even pull up inventory / crafting menu, break objects. But the second you take a step the game crashes and indicates "The software was closed because an error occured." I have attempted to restart the nintendo switch. Removed and replaced the game cartridge. Nothing has made it so that I can move from the location I was when I logged out. It is a single player world. I am inside my base. There isn't an over abundance of mobs or anything that should be creating memory issues. I do have some Redstone but nothing super intense that should be causing the game to crash.
