Minecraft lags/glitches when it is auto saving on the Nintendo switch

Again as I said, the game lags when my friends and I are playing. Usually it only happens during auto save. If we are for instance running away from mobs, during auto save, usually I freeze in game. My friend sees me freeze in her perspective but from me I am still walking or moving. Which then it turns out I am lagging or glitching and then I ended up murdered by the mob and lose all my important items. This issue makes me not want to play, which is sad cause i absolutely love crafting, but this has happened to me 5 times already. Please fix this issue. I can't lose any more enchanted items.
