my minecraft crash when get new update

Have you tried a full reinstall of the game?

Backup any data you don't want to lose, then try the following:

1. Backup your MinecraftWorlds folder (if you want to save your worlds) (Device storage > games > com.mojang > minecraftWorlds)

2. Uninstall Minecraft

3. Delete the com.mojang folder (Device storage > games > com.mojang)

4. Reinstall Minecraft

5. Run Minecraft and if it works restore your MinecraftWorlds folder

Sometimes a clean install of the game will help with these kind of issues.
