game is crashing in android phone bcoz of animation controller

hi i am developing game with unity
it a fighting game that have 30 player character to choose with
and these all character have different animation
i so make i animator controller with all the logic and
make other 29 animation override controller and attach to the all different character
and replace the animation (motion file )

than i make prefab for evry character and attack all the prefab to characterSpawner script
that script will spawn 1 enemy and 1 player according to selected character and enemy

but when i export the android apk and install in android -phone than main menu load file but when i click on play and load the fighting scene where all player and enemy character will instantiate
than game crash all the time
