My game crashes in my shared realm every time i try to open my inventory or chests

Every time I try to open chests or my inventory in my shared realm with my brother, the game completely crashes. Its extremely frustrating as him and I have put a lot of time in this realm and its making us upset as we are not able to play. Ive tried everything, restarting my pc, uninstalling and reinstalling the game, completely resetting my pc, updating everything, and nothing will work. (its on minecraft for windows)
