Minecraft continually crashes and deletes data

I've been playing Minecraft for about 9 years and have never had a problem with the game until bedrock. Ever since the hot-fix before the fox update on bedrock, Minecraft has been crashing every 20 to 30 minutes. Whenever the game crashes NPCs will despawn and random chuncks will appear throughout the world. Villagers that have been traded with, have work stations, beds, and even name tags will despawn without a trace. This will happen even in peaceful mode and if the villagers are completely walled in (Iron Golems also despawn). Horses with name tags that are leaded to a fence will also despawn and the leads are not just breaking because they're still hooked to the fence, just without an animal. The glitched chunks will spawn over a preexisting chunk and seem to be able to form with any block, natural or placed by a player. These crashes happen whenever I play the game and cause serious damage to a world.
