Nintendo Switch Minecraft Freezes while playing, crushes when I turn it off, random smaller bugs occuring while freezing

The most prominent issue is the game freezes repeatedly while I play, on random occasions. It can happen when I open a chest, or when I simply walk. I have my world as a Multiplayer world and play with a couple of friends that play on Android, so I thought I should try changing it to a Single Player world and see if anything is different. It kept freezing.

Second problem that often occurs during "freezing sessions" is random strange bugs. The most frequent one is that a Villager just disappears. It is always one of my farmer villagers that I have enclosed in a fenced area, but I noticed it's not always the same villager. I think it has also happened with a Librarian, but I'm not sure. Yesterday a second bug occured while the game was freezing. I had a pair of boots on with the Depth Strider enchantment, changed into ones with the Frost Walker Enchantment, then a few minutes later the game begun freezing repeatedly. I closed the game and then loaded the save file and to my surprise, both Boot pairs have turned into the Depth Strider one.

Lastly, more often than not when I close the game and press the Home Button the game will not close properly. This happened once or twice when I closed the game directly from the world (which I did because the game was freezing), so from then on I would only press the Home button after saving and exiting the world. Two days ago, I saved the game succesfully and went to the Minecraft menu. I made a copy of my world and then pressed the Home button and instead of closing like every other game, it loaded for a good while and then showed me the message that the game did not close properly.
