I had a system update for the switch, and then tried opening Minecraft Dungeons. It started loading, and it took an unusually long time, around 30-40 minutes, I think. After the  loading was done, I got into my account and checked my inventory. It had duplicated my current weapon, armor, bow and artifacts and also their enchantments. It now says that I'm at negative thirty-six enchantment points. There were also some minor visual glitches.
