Minecraft Event crashed and lost all progress

I was playing the new movie event, I had completed both missions. Suddenly, the game crashed and when it returned to normal, my character had lost all the XP, emeralds, upgraded tools and armor, in addition, the missions returned to the status of not completed. It's really annoying to go through this, it even discourages you from playing, I spent hours leveling up the character and lost EVERYTHING.
