Crash on death

I made a scoreboard called "Health:"(Display name) (name: hp), and when I switch into survival mode and jumped into the void(through a pre-dug hole), the game crashes on the 2nd try. The first try is perfectly normal but the second try crashes on death.
Log atached.

Note: I overflowed my experience using commands a lot before, and on death it says

Score: -64800849

Note2: After I rejoin the world I just met the normal death screen and is able to respawn normally.
