I accidentally found a workaround for this issue. It worked on my single player Bedrock game on my Android phone, but not sure about other systems.
Try to load the affected saved game. It will hang on the "loading terrain" screen.
Wait until phone screen times out and turns itself off.
Wake the phone, it should open Minecraft again, and resume trying to load the game.
This time the game successfully loaded!
